Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567626, here are decompositions:

5 + 31567621 = 31567626
7 + 31567619 = 31567626
23 + 31567603 = 31567626
67 + 31567559 = 31567626
73 + 31567553 = 31567626
113 + 31567513 = 31567626
197 + 31567429 = 31567626
199 + 31567427 = 31567626

Showing the first eight; more decompositions exist.
