Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019144, here are decompositions:

67 + 1019077 = 1019144
73 + 1019071 = 1019144
151 + 1018993 = 1019144
157 + 1018987 = 1019144
163 + 1018981 = 1019144
241 + 1018903 = 1019144
271 + 1018873 = 1019144
331 + 1018813 = 1019144

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 1,019,144 and was likely granted around 1911.

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