Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002620, here are decompositions:

37 + 1002583 = 1002620
43 + 1002577 = 1002620
67 + 1002553 = 1002620
97 + 1002523 = 1002620
103 + 1002517 = 1002620
109 + 1002511 = 1002620
127 + 1002493 = 1002620
139 + 1002481 = 1002620

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 1,002,620 and was likely granted around 1911.

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