Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001520, here are decompositions:

19 + 1001501 = 1001520
29 + 1001491 = 1001520
53 + 1001467 = 1001520
61 + 1001459 = 1001520
73 + 1001447 = 1001520
89 + 1001431 = 1001520
109 + 1001411 = 1001520
131 + 1001389 = 1001520

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 1,001,520 and was likely granted around 1911.

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