Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143784, here are decompositions:

5 + 143779 = 143784
41 + 143743 = 143784
73 + 143711 = 143784
97 + 143687 = 143784
107 + 143677 = 143784
131 + 143653 = 143784
167 + 143617 = 143784
191 + 143593 = 143784

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 143,784 and was likely granted around 1873.

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