Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588948, here are decompositions:

5 + 31588943 = 31588948
101 + 31588847 = 31588948
239 + 31588709 = 31588948
269 + 31588679 = 31588948
317 + 31588631 = 31588948
509 + 31588439 = 31588948
617 + 31588331 = 31588948
641 + 31588307 = 31588948

Showing the first eight; more decompositions exist.
