Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567650, here are decompositions:

7 + 31567643 = 31567650
13 + 31567637 = 31567650
29 + 31567621 = 31567650
31 + 31567619 = 31567650
47 + 31567603 = 31567650
97 + 31567553 = 31567650
137 + 31567513 = 31567650
139 + 31567511 = 31567650

Showing the first eight; more decompositions exist.
