Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678748, here are decompositions:

7 + 8678741 = 8678748
41 + 8678707 = 8678748
47 + 8678701 = 8678748
79 + 8678669 = 8678748
109 + 8678639 = 8678748
149 + 8678599 = 8678748
167 + 8678581 = 8678748
191 + 8678557 = 8678748

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 8,678,748 and was likely granted around 2014.

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