Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043578, here are decompositions:

47 + 1043531 = 1043578
89 + 1043489 = 1043578
227 + 1043351 = 1043578
401 + 1043177 = 1043578
461 + 1043117 = 1043578
467 + 1043111 = 1043578
617 + 1042961 = 1043578
647 + 1042931 = 1043578

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 1,043,578 and was likely granted around 1912.

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