Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588826, here are decompositions:

13 + 31588813 = 31588826
19 + 31588807 = 31588826
127 + 31588699 = 31588826
223 + 31588603 = 31588826
457 + 31588369 = 31588826
523 + 31588303 = 31588826
739 + 31588087 = 31588826
823 + 31588003 = 31588826

Showing the first eight; more decompositions exist.
