Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700154, here are decompositions:

41 + 8700113 = 8700154
83 + 8700071 = 8700154
107 + 8700047 = 8700154
173 + 8699981 = 8700154
347 + 8699807 = 8700154
383 + 8699771 = 8700154
401 + 8699753 = 8700154
431 + 8699723 = 8700154

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 8,700,154 and was likely granted around 2014.

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