Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045778, here are decompositions:

127 + 1045651 = 1045778
157 + 1045621 = 1045778
229 + 1045549 = 1045778
271 + 1045507 = 1045778
367 + 1045411 = 1045778
457 + 1045321 = 1045778
541 + 1045237 = 1045778
661 + 1045117 = 1045778

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 1,045,778 and was likely granted around 1912.

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