Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149800, here are decompositions:

29 + 149771 = 149800
41 + 149759 = 149800
71 + 149729 = 149800
83 + 149717 = 149800
89 + 149711 = 149800
173 + 149627 = 149800
197 + 149603 = 149800
239 + 149561 = 149800

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 149,800 and was likely granted around 1873.

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