Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025144, here are decompositions:

7 + 1025137 = 1025144
31 + 1025113 = 1025144
97 + 1025047 = 1025144
157 + 1024987 = 1025144
181 + 1024963 = 1025144
193 + 1024951 = 1025144
223 + 1024921 = 1025144
433 + 1024711 = 1025144

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 1,025,144 and was likely granted around 1912.

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