Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140154, here are decompositions:

11 + 140143 = 140154
31 + 140123 = 140154
43 + 140111 = 140154
83 + 140071 = 140154
97 + 140057 = 140154
101 + 140053 = 140154
163 + 139991 = 140154
167 + 139987 = 140154

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 140,154 and was likely granted around 1872.

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