Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37840, here are decompositions:
- 29 + 37811 = 37840
- 41 + 37799 = 37840
- 59 + 37781 = 37840
- 149 + 37691 = 37840
- 191 + 37649 = 37840
- 197 + 37643 = 37840
- 233 + 37607 = 37840
- 251 + 37589 = 37840
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 37840 first appears in π at position 18,585 of the decimal expansion (the 18,585ordinal-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.
