Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001530, here are decompositions:

3 + 1001527 = 1001530
29 + 1001501 = 1001530
71 + 1001459 = 1001530
83 + 1001447 = 1001530
149 + 1001381 = 1001530
227 + 1001303 = 1001530
239 + 1001291 = 1001530
251 + 1001279 = 1001530

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 1,001,530 and was likely granted around 1911.

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