Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140452, here are decompositions:

3 + 140449 = 140452
29 + 140423 = 140452
41 + 140411 = 140452
71 + 140381 = 140452
89 + 140363 = 140452
101 + 140351 = 140452
113 + 140339 = 140452
131 + 140321 = 140452

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 140,452 and was likely granted around 1872.

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