Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021502, here are decompositions:

19 + 1021483 = 1021502
61 + 1021441 = 1021502
73 + 1021429 = 1021502
199 + 1021303 = 1021502
211 + 1021291 = 1021502
241 + 1021261 = 1021502
373 + 1021129 = 1021502
379 + 1021123 = 1021502

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 1,021,502 and was likely granted around 1912.

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