Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588432, here are decompositions:

101 + 31588331 = 31588432
179 + 31588253 = 31588432
233 + 31588199 = 31588432
509 + 31587923 = 31588432
521 + 31587911 = 31588432
653 + 31587779 = 31588432
683 + 31587749 = 31588432
773 + 31587659 = 31588432

Showing the first eight; more decompositions exist.
