Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567924, here are decompositions:

41 + 31567883 = 31567924
251 + 31567673 = 31567924
281 + 31567643 = 31567924
653 + 31567271 = 31567924
683 + 31567241 = 31567924
881 + 31567043 = 31567924
1013 + 31566911 = 31567924
1061 + 31566863 = 31567924

Showing the first eight; more decompositions exist.
