Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588456, here are decompositions:

17 + 31588439 = 31588456
89 + 31588367 = 31588456
149 + 31588307 = 31588456
257 + 31588199 = 31588456
353 + 31588103 = 31588456
563 + 31587893 = 31588456
677 + 31587779 = 31588456
719 + 31587737 = 31588456

Showing the first eight; more decompositions exist.
