Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496448, here are decompositions:

7 + 31496441 = 31496448
19 + 31496429 = 31496448
29 + 31496419 = 31496448
31 + 31496417 = 31496448
59 + 31496389 = 31496448
79 + 31496369 = 31496448
127 + 31496321 = 31496448
131 + 31496317 = 31496448

Showing the first eight; more decompositions exist.
