Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180610, here are decompositions:

41 + 180569 = 180610
47 + 180563 = 180610
71 + 180539 = 180610
107 + 180503 = 180610
113 + 180497 = 180610
137 + 180473 = 180610
173 + 180437 = 180610
191 + 180419 = 180610

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 180,610 and was likely granted around 1875.

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