Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180550, here are decompositions:

3 + 180547 = 180550
11 + 180539 = 180550
17 + 180533 = 180550
47 + 180503 = 180550
53 + 180497 = 180550
59 + 180491 = 180550
113 + 180437 = 180550
131 + 180419 = 180550

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 180,550 and was likely granted around 1875.

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