Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552568, here are decompositions:

31 + 31552537 = 31552568
79 + 31552489 = 31552568
139 + 31552429 = 31552568
181 + 31552387 = 31552568
331 + 31552237 = 31552568
499 + 31552069 = 31552568
571 + 31551997 = 31552568
631 + 31551937 = 31552568

Showing the first eight; more decompositions exist.
