Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177864, here are decompositions:
- 23 + 177841 = 177864
- 41 + 177823 = 177864
- 53 + 177811 = 177864
- 67 + 177797 = 177864
- 73 + 177791 = 177864
- 101 + 177763 = 177864
- 103 + 177761 = 177864
- 173 + 177691 = 177864
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 177,864 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 177864 first appears in π at position 98,838 of the decimal expansion (the 98,838ordinal-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.
