Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494966, here are decompositions:

17 + 31494949 = 31494966
23 + 31494943 = 31494966
29 + 31494937 = 31494966
43 + 31494923 = 31494966
47 + 31494919 = 31494966
59 + 31494907 = 31494966
79 + 31494887 = 31494966
149 + 31494817 = 31494966

Showing the first eight; more decompositions exist.
