Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563016, here are decompositions:

3 + 31563013 = 31563016
29 + 31562987 = 31563016
167 + 31562849 = 31563016
239 + 31562777 = 31563016
389 + 31562627 = 31563016
449 + 31562567 = 31563016
587 + 31562429 = 31563016
593 + 31562423 = 31563016

Showing the first eight; more decompositions exist.
