Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180260, here are decompositions:

13 + 180247 = 180260
19 + 180241 = 180260
79 + 180181 = 180260
163 + 180097 = 180260
271 + 179989 = 180260
307 + 179953 = 180260
313 + 179947 = 180260
337 + 179923 = 180260

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 180,260 and was likely granted around 1875.

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