Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490652, here are decompositions:

19 + 31490633 = 31490652
23 + 31490629 = 31490652
29 + 31490623 = 31490652
31 + 31490621 = 31490652
43 + 31490609 = 31490652
59 + 31490593 = 31490652
79 + 31490573 = 31490652
163 + 31490489 = 31490652

Showing the first eight; more decompositions exist.
