Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45780, here are decompositions:
- 13 + 45767 = 45780
- 17 + 45763 = 45780
- 23 + 45757 = 45780
- 29 + 45751 = 45780
- 43 + 45737 = 45780
- 73 + 45707 = 45780
- 83 + 45697 = 45780
- 89 + 45691 = 45780
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 45780 first appears in π at position 123,750 of the decimal expansion (the 123,750ordinal-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.
