Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151604, here are decompositions:
- 7 + 151597 = 151604
- 31 + 151573 = 151604
- 43 + 151561 = 151604
- 67 + 151537 = 151604
- 73 + 151531 = 151604
- 97 + 151507 = 151604
- 127 + 151477 = 151604
- 181 + 151423 = 151604
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 151,604 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 151604 first appears in π at position 291,995 of the decimal expansion (the 291,995ordinal-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.
