My gmail.com address begins with a word found by cyclicly extending my display name here ('bgins') to the next prime length, or from the sequence of digits ($a_i$), interpreted as letter numbers, found by converting $2751020930=\sum a_i b^i$ to base $b=27$, for example with sage:

''.join([chr(ord('a')+_-1) for _ in 2751020930.digits(base=27)])
