Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109142, here are decompositions:
- 3 + 109139 = 109142
- 31 + 109111 = 109142
- 79 + 109063 = 109142
- 151 + 108991 = 109142
- 181 + 108961 = 109142
- 193 + 108949 = 109142
- 199 + 108943 = 109142
- 349 + 108793 = 109142
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 109,142 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 109142 first appears in π at position 912,704 of the decimal expansion (the 912,704ordinal-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.
