Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150146, here are decompositions:

79 + 150067 = 150146
193 + 149953 = 150146
307 + 149839 = 150146
379 + 149767 = 150146
397 + 149749 = 150146
433 + 149713 = 150146
457 + 149689 = 150146
523 + 149623 = 150146

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 150,146 and was likely granted around 1873.

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