Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157464, here are decompositions:
- 7 + 157457 = 157464
- 31 + 157433 = 157464
- 37 + 157427 = 157464
- 53 + 157411 = 157464
- 71 + 157393 = 157464
- 101 + 157363 = 157464
- 113 + 157351 = 157464
- 137 + 157327 = 157464
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 157,464 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 157464 first appears in π at position 756,788 of the decimal expansion (the 756,788ordinal-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.
