Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180502, here are decompositions:

5 + 180497 = 180502
11 + 180491 = 180502
29 + 180473 = 180502
83 + 180419 = 180502
89 + 180413 = 180502
131 + 180371 = 180502
191 + 180311 = 180502
239 + 180263 = 180502

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 180,502 and was likely granted around 1875.

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