Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130144, here are decompositions:

17 + 130127 = 130144
23 + 130121 = 130144
71 + 130073 = 130144
101 + 130043 = 130144
173 + 129971 = 130144
191 + 129953 = 130144
227 + 129917 = 130144
251 + 129893 = 130144

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 130,144 and was likely granted around 1872.

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