Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70072, here are decompositions:
- 5 + 70067 = 70072
- 11 + 70061 = 70072
- 53 + 70019 = 70072
- 71 + 70001 = 70072
- 113 + 69959 = 70072
- 131 + 69941 = 70072
- 173 + 69899 = 70072
- 239 + 69833 = 70072
Showing the first eight; more decompositions exist.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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 70072 first appears in π at position 236,765 of the decimal expansion (the 236,765ordinal-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.
