Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103642, here are decompositions:

23 + 103619 = 103642
29 + 103613 = 103642
59 + 103583 = 103642
89 + 103553 = 103642
113 + 103529 = 103642
131 + 103511 = 103642
191 + 103451 = 103642
233 + 103409 = 103642

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 103.642 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
