Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687072, here are decompositions:

3 + 8687069 = 8687072
73 + 8686999 = 8687072
421 + 8686651 = 8687072
571 + 8686501 = 8687072
601 + 8686471 = 8687072
613 + 8686459 = 8687072
859 + 8686213 = 8687072
883 + 8686189 = 8687072

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 8,687,072 and was likely granted around 2014.

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