Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567724, here are decompositions:

7 + 31567717 = 31567724
31 + 31567693 = 31567724
37 + 31567687 = 31567724
43 + 31567681 = 31567724
103 + 31567621 = 31567724
211 + 31567513 = 31567724
313 + 31567411 = 31567724
457 + 31567267 = 31567724

Showing the first eight; more decompositions exist.
