Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104942, here are decompositions:
- 31 + 104911 = 104942
- 73 + 104869 = 104942
- 139 + 104803 = 104942
- 163 + 104779 = 104942
- 181 + 104761 = 104942
- 199 + 104743 = 104942
- 241 + 104701 = 104942
- 283 + 104659 = 104942
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 104,942 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 104942 first appears in π at position 69,098 of the decimal expansion (the 69,098ordinal-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.
