Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592908, here are decompositions:

59 + 31592849 = 31592908
257 + 31592651 = 31592908
419 + 31592489 = 31592908
461 + 31592447 = 31592908
491 + 31592417 = 31592908
617 + 31592291 = 31592908
857 + 31592051 = 31592908
911 + 31591997 = 31592908

Showing the first eight; more decompositions exist.
