Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611250, here are decompositions:

3 + 8611247 = 8611250
31 + 8611219 = 8611250
103 + 8611147 = 8611250
313 + 8610937 = 8611250
331 + 8610919 = 8611250
337 + 8610913 = 8611250
379 + 8610871 = 8611250
421 + 8610829 = 8611250

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 8,611,250 and was likely granted around 2013.

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