Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670040, here are decompositions:

3 + 8670037 = 8670040
11 + 8670029 = 8670040
47 + 8669993 = 8670040
59 + 8669981 = 8670040
101 + 8669939 = 8670040
179 + 8669861 = 8670040
263 + 8669777 = 8670040
383 + 8669657 = 8670040

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 8 670 040 and was likely granted around 2014.

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