Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712000, here are decompositions:

13 + 8711987 = 8712000
29 + 8711971 = 8712000
47 + 8711953 = 8712000
67 + 8711933 = 8712000
79 + 8711921 = 8712000
103 + 8711897 = 8712000
113 + 8711887 = 8712000
131 + 8711869 = 8712000

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 8,712,000 and was likely granted around 2014.

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