Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476448, here are decompositions:

11 + 31476437 = 31476448
131 + 31476317 = 31476448
197 + 31476251 = 31476448
389 + 31476059 = 31476448
431 + 31476017 = 31476448
599 + 31475849 = 31476448
677 + 31475771 = 31476448
977 + 31475471 = 31476448

Showing the first eight; more decompositions exist.
