Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588662, here are decompositions:

5 + 31588657 = 31588662
19 + 31588643 = 31588662
31 + 31588631 = 31588662
59 + 31588603 = 31588662
101 + 31588561 = 31588662
139 + 31588523 = 31588662
179 + 31588483 = 31588662
191 + 31588471 = 31588662

Showing the first eight; more decompositions exist.
