Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72300, here are decompositions:
- 13 + 72287 = 72300
- 23 + 72277 = 72300
- 29 + 72271 = 72300
- 31 + 72269 = 72300
- 47 + 72253 = 72300
- 71 + 72229 = 72300
- 73 + 72227 = 72300
- 79 + 72221 = 72300
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 72300 first appears in π at position 153,181 of the decimal expansion (the 153,181ordinal-suffix:st 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.
