Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180102, here are decompositions:

5 + 180097 = 180102
29 + 180073 = 180102
31 + 180071 = 180102
59 + 180043 = 180102
79 + 180023 = 180102
101 + 180001 = 180102
103 + 179999 = 180102
113 + 179989 = 180102

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 180,102 and was likely granted around 1875.

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