Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662178, here are decompositions:

157 + 8662021 = 8662178
181 + 8661997 = 8662178
277 + 8661901 = 8662178
307 + 8661871 = 8662178
337 + 8661841 = 8662178
379 + 8661799 = 8662178
409 + 8661769 = 8662178
601 + 8661577 = 8662178

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 8,662,178 and was likely granted around 2014.

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