Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567722, here are decompositions:

5 + 31567717 = 31567722
13 + 31567709 = 31567722
23 + 31567699 = 31567722
29 + 31567693 = 31567722
41 + 31567681 = 31567722
73 + 31567649 = 31567722
79 + 31567643 = 31567722
101 + 31567621 = 31567722

Showing the first eight; more decompositions exist.
