Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129850, here are decompositions:

47 + 129803 = 129850
101 + 129749 = 129850
113 + 129737 = 129850
131 + 129719 = 129850
179 + 129671 = 129850
257 + 129593 = 129850
263 + 129587 = 129850
269 + 129581 = 129850

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 129,850 and was likely granted around 1872.

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