Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588610, here are decompositions:

3 + 31588607 = 31588610
7 + 31588603 = 31588610
127 + 31588483 = 31588610
139 + 31588471 = 31588610
211 + 31588399 = 31588610
241 + 31588369 = 31588610
307 + 31588303 = 31588610
409 + 31588201 = 31588610

Showing the first eight; more decompositions exist.
