Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670490, here are decompositions:

83 + 8670407 = 8670490
137 + 8670353 = 8670490
233 + 8670257 = 8670490
251 + 8670239 = 8670490
293 + 8670197 = 8670490
383 + 8670107 = 8670490
401 + 8670089 = 8670490
419 + 8670071 = 8670490

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 8,670,490 and was likely granted around 2014.

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