Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588646, here are decompositions:

3 + 31588643 = 31588646
43 + 31588603 = 31588646
163 + 31588483 = 31588646
277 + 31588369 = 31588646
379 + 31588267 = 31588646
643 + 31588003 = 31588646
769 + 31587877 = 31588646
787 + 31587859 = 31588646

Showing the first eight; more decompositions exist.
