Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671554, here are decompositions:

5 + 8671549 = 8671554
37 + 8671517 = 8671554
43 + 8671511 = 8671554
53 + 8671501 = 8671554
83 + 8671471 = 8671554
97 + 8671457 = 8671554
107 + 8671447 = 8671554
113 + 8671441 = 8671554

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 8,671,554 and was likely granted around 2014.

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