Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142764, here are decompositions:

5 + 142759 = 142764
7 + 142757 = 142764
31 + 142733 = 142764
53 + 142711 = 142764
67 + 142697 = 142764
107 + 142657 = 142764
157 + 142607 = 142764
163 + 142601 = 142764

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 142,764 and was likely granted around 1872.

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