Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678256, here are decompositions:

19 + 8678237 = 8678256
43 + 8678213 = 8678256
53 + 8678203 = 8678256
107 + 8678149 = 8678256
109 + 8678147 = 8678256
127 + 8678129 = 8678256
163 + 8678093 = 8678256
173 + 8678083 = 8678256

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 8,678,256 and was likely granted around 2014.

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