Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180038, here are decompositions:

31 + 180007 = 180038
37 + 180001 = 180038
139 + 179899 = 180038
211 + 179827 = 180038
349 + 179689 = 180038
367 + 179671 = 180038
379 + 179659 = 180038
457 + 179581 = 180038

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 180,038 and was likely granted around 1875.

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