Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157004, here are decompositions:
- 37 + 156967 = 157004
- 61 + 156943 = 157004
- 103 + 156901 = 157004
- 163 + 156841 = 157004
- 181 + 156823 = 157004
- 223 + 156781 = 157004
- 271 + 156733 = 157004
- 277 + 156727 = 157004
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 157,004 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 157004 first appears in π at position 218,660 of the decimal expansion (the 218,660ordinal-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.
