Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042042, here are decompositions:

3 + 1042039 = 1042042
41 + 1042001 = 1042042
59 + 1041983 = 1042042
149 + 1041893 = 1042042
173 + 1041869 = 1042042
179 + 1041863 = 1042042
263 + 1041779 = 1042042
311 + 1041731 = 1042042

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 1,042,042 and was likely granted around 1912.

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