Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731000, here are decompositions:

17 + 8730983 = 8731000
23 + 8730977 = 8731000
53 + 8730947 = 8731000
71 + 8730929 = 8731000
107 + 8730893 = 8731000
137 + 8730863 = 8731000
149 + 8730851 = 8731000
197 + 8730803 = 8731000

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 8,731,000 and was likely granted around 2014.

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