Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673138, here are decompositions:

7 + 8673131 = 8673138
11 + 8673127 = 8673138
17 + 8673121 = 8673138
29 + 8673109 = 8673138
31 + 8673107 = 8673138
41 + 8673097 = 8673138
101 + 8673037 = 8673138
109 + 8673029 = 8673138

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 8,673,138 and was likely granted around 2014.

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