Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574526, here are decompositions:

19 + 31574507 = 31574526
29 + 31574497 = 31574526
37 + 31574489 = 31574526
47 + 31574479 = 31574526
59 + 31574467 = 31574526
73 + 31574453 = 31574526
83 + 31574443 = 31574526
89 + 31574437 = 31574526

Showing the first eight; more decompositions exist.
