Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180230, here are decompositions:

19 + 180211 = 180230
157 + 180073 = 180230
223 + 180007 = 180230
229 + 180001 = 180230
241 + 179989 = 180230
277 + 179953 = 180230
283 + 179947 = 180230
307 + 179923 = 180230

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 180,230 and was likely granted around 1875.

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