Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460792, here are decompositions:

211 + 31460581 = 31460792
241 + 31460551 = 31460792
283 + 31460509 = 31460792
379 + 31460413 = 31460792
463 + 31460329 = 31460792
499 + 31460293 = 31460792
619 + 31460173 = 31460792
739 + 31460053 = 31460792

Showing the first eight; more decompositions exist.
