Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505676, here are decompositions:

17 + 31505659 = 31505676
19 + 31505657 = 31505676
43 + 31505633 = 31505676
53 + 31505623 = 31505676
67 + 31505609 = 31505676
107 + 31505569 = 31505676
109 + 31505567 = 31505676
149 + 31505527 = 31505676

Showing the first eight; more decompositions exist.
