Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567662, here are decompositions:

13 + 31567649 = 31567662
19 + 31567643 = 31567662
41 + 31567621 = 31567662
43 + 31567619 = 31567662
59 + 31567603 = 31567662
103 + 31567559 = 31567662
109 + 31567553 = 31567662
149 + 31567513 = 31567662

Showing the first eight; more decompositions exist.
