Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662220, here are decompositions:

3 + 8662217 = 8662220
19 + 8662201 = 8662220
31 + 8662189 = 8662220
43 + 8662177 = 8662220
67 + 8662153 = 8662220
163 + 8662057 = 8662220
199 + 8662021 = 8662220
211 + 8662009 = 8662220

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 8,662,220 and was likely granted around 2014.

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