Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43070, here are decompositions:
- 3 + 43067 = 43070
- 7 + 43063 = 43070
- 19 + 43051 = 43070
- 67 + 43003 = 43070
- 103 + 42967 = 43070
- 109 + 42961 = 43070
- 127 + 42943 = 43070
- 211 + 42859 = 43070
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.168.62.

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 43070 first appears in π at position 123,426 of the decimal expansion (the 123,426ordinal-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.
