Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500870, here are decompositions:

31 + 500839 = 500870
61 + 500809 = 500870
79 + 500791 = 500870
151 + 500719 = 500870
157 + 500713 = 500870
193 + 500677 = 500870
199 + 500671 = 500870
241 + 500629 = 500870

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 500,870 and was likely granted around 1893.

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