Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025972, here are decompositions:

43 + 1025929 = 1025972
61 + 1025911 = 1025972
223 + 1025749 = 1025972
313 + 1025659 = 1025972
331 + 1025641 = 1025972
349 + 1025623 = 1025972
421 + 1025551 = 1025972
463 + 1025509 = 1025972

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 1,025,972 and was likely granted around 1912.

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