Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501920, here are decompositions:

31 + 501889 = 501920
79 + 501841 = 501920
103 + 501817 = 501920
151 + 501769 = 501920
229 + 501691 = 501920
283 + 501637 = 501920
409 + 501511 = 501920
457 + 501463 = 501920

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 501,920 and was likely granted around 1893.

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