Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670238, here are decompositions:

41 + 8670197 = 8670238
47 + 8670191 = 8670238
131 + 8670107 = 8670238
149 + 8670089 = 8670238
167 + 8670071 = 8670238
197 + 8670041 = 8670238
257 + 8669981 = 8670238
359 + 8669879 = 8670238

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 8,670,238 and was likely granted around 2014.

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