Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740000, here are decompositions:

47 + 8739953 = 8740000
83 + 8739917 = 8740000
89 + 8739911 = 8740000
131 + 8739869 = 8740000
149 + 8739851 = 8740000
173 + 8739827 = 8740000
179 + 8739821 = 8740000
197 + 8739803 = 8740000

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 8,740,000 and was likely granted around 2014.

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