Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043158, here are decompositions:

41 + 1043117 = 1043158
47 + 1043111 = 1043158
197 + 1042961 = 1043158
227 + 1042931 = 1043158
257 + 1042901 = 1043158
359 + 1042799 = 1043158
449 + 1042709 = 1043158
587 + 1042571 = 1043158

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 1,043,158 and was likely granted around 1912.

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