Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111942, here are decompositions:
- 23 + 111919 = 111942
- 29 + 111913 = 111942
- 71 + 111871 = 111942
- 73 + 111869 = 111942
- 79 + 111863 = 111942
- 109 + 111833 = 111942
- 113 + 111829 = 111942
- 151 + 111791 = 111942
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 111,942 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 111942 first appears in π at position 109,027 of the decimal expansion (the 109,027ordinal-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.
