Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567684, here are decompositions:

3 + 31567681 = 31567684
11 + 31567673 = 31567684
41 + 31567643 = 31567684
47 + 31567637 = 31567684
131 + 31567553 = 31567684
173 + 31567511 = 31567684
233 + 31567451 = 31567684
257 + 31567427 = 31567684

Showing the first eight; more decompositions exist.
