Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592688, here are decompositions:

5 + 31592683 = 31592688
11 + 31592677 = 31592688
37 + 31592651 = 31592688
47 + 31592641 = 31592688
67 + 31592621 = 31592688
89 + 31592599 = 31592688
131 + 31592557 = 31592688
137 + 31592551 = 31592688

Showing the first eight; more decompositions exist.
