Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157104, here are decompositions:
- 23 + 157081 = 157104
- 43 + 157061 = 157104
- 47 + 157057 = 157104
- 53 + 157051 = 157104
- 67 + 157037 = 157104
- 97 + 157007 = 157104
- 137 + 156967 = 157104
- 163 + 156941 = 157104
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 157,104 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 157104 first appears in π at position 379,327 of the decimal expansion (the 379,327ordinal-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.
