Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167742, here are decompositions:
- 13 + 167729 = 167742
- 31 + 167711 = 167742
- 59 + 167683 = 167742
- 79 + 167663 = 167742
- 101 + 167641 = 167742
- 109 + 167633 = 167742
- 131 + 167611 = 167742
- 149 + 167593 = 167742
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 167,742 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 167742 first appears in π at position 370,009 of the decimal expansion (the 370,009ordinal-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.
