Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567754, here are decompositions:

13 + 31567741 = 31567754
37 + 31567717 = 31567754
61 + 31567693 = 31567754
67 + 31567687 = 31567754
73 + 31567681 = 31567754
151 + 31567603 = 31567754
241 + 31567513 = 31567754
457 + 31567297 = 31567754

Showing the first eight; more decompositions exist.
