Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750000, here are decompositions:

19 + 8749981 = 8750000
73 + 8749927 = 8750000
79 + 8749921 = 8750000
97 + 8749903 = 8750000
109 + 8749891 = 8750000
163 + 8749837 = 8750000
211 + 8749789 = 8750000
229 + 8749771 = 8750000

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 8,750,000 and was likely granted around 2014.

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