Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592810, here are decompositions:

13 + 31592797 = 31592810
31 + 31592779 = 31592810
37 + 31592773 = 31592810
127 + 31592683 = 31592810
211 + 31592599 = 31592810
373 + 31592437 = 31592810
421 + 31592389 = 31592810
433 + 31592377 = 31592810

Showing the first eight; more decompositions exist.
