Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592658, here are decompositions:

7 + 31592651 = 31592658
17 + 31592641 = 31592658
37 + 31592621 = 31592658
59 + 31592599 = 31592658
101 + 31592557 = 31592658
107 + 31592551 = 31592658
127 + 31592531 = 31592658
191 + 31592467 = 31592658

Showing the first eight; more decompositions exist.
