Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945020, here are decompositions:

67 + 944953 = 945020
127 + 944893 = 945020
163 + 944857 = 945020
199 + 944821 = 945020
331 + 944689 = 945020
457 + 944563 = 945020
487 + 944533 = 945020
499 + 944521 = 945020

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 945,020 and was likely granted around 1909.

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