Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002880, here are decompositions:

17 + 1002863 = 1002880
23 + 1002857 = 1002880
29 + 1002851 = 1002880
59 + 1002821 = 1002880
71 + 1002809 = 1002880
83 + 1002797 = 1002880
107 + 1002773 = 1002880
113 + 1002767 = 1002880

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 1,002,880 and was likely granted around 1911.

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