Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142500, here are decompositions:

31 + 142469 = 142500
47 + 142453 = 142500
67 + 142433 = 142500
73 + 142427 = 142500
79 + 142421 = 142500
97 + 142403 = 142500
109 + 142391 = 142500
131 + 142369 = 142500

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 142,500 and was likely granted around 1872.

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