Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588682, here are decompositions:

3 + 31588679 = 31588682
79 + 31588603 = 31588682
199 + 31588483 = 31588682
211 + 31588471 = 31588682
241 + 31588441 = 31588682
283 + 31588399 = 31588682
313 + 31588369 = 31588682
331 + 31588351 = 31588682

Showing the first eight; more decompositions exist.
