Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687328, here are decompositions:

7 + 8687321 = 8687328
11 + 8687317 = 8687328
19 + 8687309 = 8687328
29 + 8687299 = 8687328
37 + 8687291 = 8687328
79 + 8687249 = 8687328
101 + 8687227 = 8687328
131 + 8687197 = 8687328

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 8,687,328 and was likely granted around 2014.

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