Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104642, here are decompositions:
- 3 + 104639 = 104642
- 19 + 104623 = 104642
- 151 + 104491 = 104642
- 163 + 104479 = 104642
- 331 + 104311 = 104642
- 409 + 104233 = 104642
- 463 + 104179 = 104642
- 523 + 104119 = 104642
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 104,642 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 104642 first appears in π at position 450,971 of the decimal expansion (the 450,971ordinal-suffix:st 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.
