Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567930, here are decompositions:

47 + 31567883 = 31567930
71 + 31567859 = 31567930
257 + 31567673 = 31567930
281 + 31567649 = 31567930
293 + 31567637 = 31567930
311 + 31567619 = 31567930
419 + 31567511 = 31567930
479 + 31567451 = 31567930

Showing the first eight; more decompositions exist.
