Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567692, here are decompositions:

5 + 31567687 = 31567692
11 + 31567681 = 31567692
19 + 31567673 = 31567692
43 + 31567649 = 31567692
71 + 31567621 = 31567692
73 + 31567619 = 31567692
89 + 31567603 = 31567692
139 + 31567553 = 31567692

Showing the first eight; more decompositions exist.
