Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015150, here are decompositions:

11 + 1015139 = 1015150
23 + 1015127 = 1015150
53 + 1015097 = 1015150
83 + 1015067 = 1015150
89 + 1015061 = 1015150
107 + 1015043 = 1015150
197 + 1014953 = 1015150
263 + 1014887 = 1015150

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 1,015,150 and was likely granted around 1911.

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