Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002920, here are decompositions:

3 + 1002917 = 1002920
7 + 1002913 = 1002920
67 + 1002853 = 1002920
103 + 1002817 = 1002920
151 + 1002769 = 1002920
181 + 1002739 = 1002920
199 + 1002721 = 1002920
211 + 1002709 = 1002920

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 1,002,920 and was likely granted around 1911.

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