Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003620, here are decompositions:

11 + 1003609 = 1003620
19 + 1003601 = 1003620
31 + 1003589 = 1003620
71 + 1003549 = 1003620
103 + 1003517 = 1003620
113 + 1003507 = 1003620
151 + 1003469 = 1003620
157 + 1003463 = 1003620

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 1,003,620 and was likely granted around 1911.

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