Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000154, here are decompositions:

3 + 1000151 = 1000154
37 + 1000117 = 1000154
73 + 1000081 = 1000154
151 + 1000003 = 1000154
193 + 999961 = 1000154
223 + 999931 = 1000154
271 + 999883 = 1000154
433 + 999721 = 1000154

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 1,000,154 and was likely granted around 1911.

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