Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592666, here are decompositions:

3 + 31592663 = 31592666
67 + 31592599 = 31592666
109 + 31592557 = 31592666
199 + 31592467 = 31592666
229 + 31592437 = 31592666
277 + 31592389 = 31592666
409 + 31592257 = 31592666
463 + 31592203 = 31592666

Showing the first eight; more decompositions exist.
