Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662042, here are decompositions:

5 + 8662037 = 8662042
23 + 8662019 = 8662042
89 + 8661953 = 8662042
101 + 8661941 = 8662042
353 + 8661689 = 8662042
359 + 8661683 = 8662042
401 + 8661641 = 8662042
419 + 8661623 = 8662042

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 8,662,042 and was likely granted around 2014.

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