Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671240, here are decompositions:

47 + 8671193 = 8671240
89 + 8671151 = 8671240
107 + 8671133 = 8671240
113 + 8671127 = 8671240
173 + 8671067 = 8671240
233 + 8671007 = 8671240
251 + 8670989 = 8671240
293 + 8670947 = 8671240

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 8,671,240 and was likely granted around 2014.

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