Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670380, here are decompositions:

7 + 8670373 = 8670380
67 + 8670313 = 8670380
79 + 8670301 = 8670380
223 + 8670157 = 8670380
349 + 8670031 = 8670380
373 + 8670007 = 8670380
457 + 8669923 = 8670380
487 + 8669893 = 8670380

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 8,670,380 and was likely granted around 2014.

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