Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592660, here are decompositions:

19 + 31592641 = 31592660
61 + 31592599 = 31592660
103 + 31592557 = 31592660
109 + 31592551 = 31592660
193 + 31592467 = 31592660
223 + 31592437 = 31592660
271 + 31592389 = 31592660
283 + 31592377 = 31592660

Showing the first eight; more decompositions exist.
