Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588634, here are decompositions:

3 + 31588631 = 31588634
31 + 31588603 = 31588634
73 + 31588561 = 31588634
151 + 31588483 = 31588634
163 + 31588471 = 31588634
193 + 31588441 = 31588634
277 + 31588357 = 31588634
283 + 31588351 = 31588634

Showing the first eight; more decompositions exist.
