Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588722, here are decompositions:

13 + 31588709 = 31588722
23 + 31588699 = 31588722
29 + 31588693 = 31588722
43 + 31588679 = 31588722
79 + 31588643 = 31588722
199 + 31588523 = 31588722
229 + 31588493 = 31588722
239 + 31588483 = 31588722

Showing the first eight; more decompositions exist.
