Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480652, here are decompositions:

3 + 31480649 = 31480652
13 + 31480639 = 31480652
31 + 31480621 = 31480652
211 + 31480441 = 31480652
271 + 31480381 = 31480652
283 + 31480369 = 31480652
523 + 31480129 = 31480652
631 + 31480021 = 31480652

Showing the first eight; more decompositions exist.
