Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167730, here are decompositions:
- 19 + 167711 = 167730
- 47 + 167683 = 167730
- 53 + 167677 = 167730
- 67 + 167663 = 167730
- 89 + 167641 = 167730
- 97 + 167633 = 167730
- 103 + 167627 = 167730
- 107 + 167623 = 167730
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 167,730 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 167730 first appears in π at position 131,374 of the decimal expansion (the 131,374ordinal-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.
