Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012, here are decompositions:
- 3 + 1009 = 1012
- 29 + 983 = 1012
- 41 + 971 = 1012
- 59 + 953 = 1012
- 71 + 941 = 1012
- 83 + 929 = 1012
- 101 + 911 = 1012
- 131 + 881 = 1012
Showing the first eight; more decompositions exist.

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 1012 first appears in π at position 8,617 of the decimal expansion (the 8,617ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
