Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177804, here are decompositions:
- 7 + 177797 = 177804
- 13 + 177791 = 177804
- 17 + 177787 = 177804
- 41 + 177763 = 177804
- 43 + 177761 = 177804
- 61 + 177743 = 177804
- 113 + 177691 = 177804
- 127 + 177677 = 177804
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 177,804 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 177804 first appears in π at position 538,584 of the decimal expansion (the 538,584ordinal-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.
