Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588132, here are decompositions:

3 + 31588129 = 31588132
29 + 31588103 = 31588132
71 + 31588061 = 31588132
113 + 31588019 = 31588132
239 + 31587893 = 31588132
353 + 31587779 = 31588132
383 + 31587749 = 31588132
431 + 31587701 = 31588132

Showing the first eight; more decompositions exist.
