Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021516, here are decompositions:

29 + 1021487 = 1021516
53 + 1021463 = 1021516
59 + 1021457 = 1021516
113 + 1021403 = 1021516
149 + 1021367 = 1021516
227 + 1021289 = 1021516
233 + 1021283 = 1021516
257 + 1021259 = 1021516

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 1,021,516 and was likely granted around 1912.

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