Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156404, here are decompositions:
- 43 + 156361 = 156404
- 97 + 156307 = 156404
- 151 + 156253 = 156404
- 163 + 156241 = 156404
- 277 + 156127 = 156404
- 397 + 156007 = 156404
- 541 + 155863 = 156404
- 571 + 155833 = 156404
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 156,404 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 156404 first appears in π at position 902,466 of the decimal expansion (the 902,466ordinal-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.
