Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574496, here are decompositions:

7 + 31574489 = 31574496
17 + 31574479 = 31574496
29 + 31574467 = 31574496
43 + 31574453 = 31574496
47 + 31574449 = 31574496
53 + 31574443 = 31574496
59 + 31574437 = 31574496
67 + 31574429 = 31574496

Showing the first eight; more decompositions exist.
