Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672870, here are decompositions:

79 + 8672791 = 8672870
97 + 8672773 = 8672870
103 + 8672767 = 8672870
139 + 8672731 = 8672870
163 + 8672707 = 8672870
211 + 8672659 = 8672870
223 + 8672647 = 8672870
229 + 8672641 = 8672870

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 8,672,870 and was likely granted around 2014.

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