Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180516, here are decompositions:

5 + 180511 = 180516
13 + 180503 = 180516
19 + 180497 = 180516
43 + 180473 = 180516
53 + 180463 = 180516
79 + 180437 = 180516
97 + 180419 = 180516
103 + 180413 = 180516

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 180,516 and was likely granted around 1875.

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