Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515004, here are decompositions:

37 + 514967 = 515004
71 + 514933 = 515004
101 + 514903 = 515004
131 + 514873 = 515004
137 + 514867 = 515004
151 + 514853 = 515004
157 + 514847 = 515004
163 + 514841 = 515004

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 515,004 and was likely granted around 1894.

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