Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961600, here are decompositions:

53 + 961547 = 961600
71 + 961529 = 961600
89 + 961511 = 961600
113 + 961487 = 961600
149 + 961451 = 961600
173 + 961427 = 961600
281 + 961319 = 961600
317 + 961283 = 961600

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 961,600 and was likely granted around 1910.

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