Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592708, here are decompositions:

31 + 31592677 = 31592708
67 + 31592641 = 31592708
109 + 31592599 = 31592708
151 + 31592557 = 31592708
157 + 31592551 = 31592708
241 + 31592467 = 31592708
271 + 31592437 = 31592708
331 + 31592377 = 31592708

Showing the first eight; more decompositions exist.
