Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588658, here are decompositions:

97 + 31588561 = 31588658
307 + 31588351 = 31588658
337 + 31588321 = 31588658
457 + 31588201 = 31588658
487 + 31588171 = 31588658
571 + 31588087 = 31588658
709 + 31587949 = 31588658
859 + 31587799 = 31588658

Showing the first eight; more decompositions exist.
