Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588712, here are decompositions:

3 + 31588709 = 31588712
13 + 31588699 = 31588712
19 + 31588693 = 31588712
109 + 31588603 = 31588712
151 + 31588561 = 31588712
229 + 31588483 = 31588712
241 + 31588471 = 31588712
271 + 31588441 = 31588712

Showing the first eight; more decompositions exist.
