Goldbach decomposition

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.

Possible US patent number

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.
