Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567702, here are decompositions:

3 + 31567699 = 31567702
29 + 31567673 = 31567702
53 + 31567649 = 31567702
59 + 31567643 = 31567702
83 + 31567619 = 31567702
149 + 31567553 = 31567702
191 + 31567511 = 31567702
251 + 31567451 = 31567702

Showing the first eight; more decompositions exist.
