Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494954, here are decompositions:

5 + 31494949 = 31494954
11 + 31494943 = 31494954
17 + 31494937 = 31494954
31 + 31494923 = 31494954
47 + 31494907 = 31494954
67 + 31494887 = 31494954
137 + 31494817 = 31494954
173 + 31494781 = 31494954

Showing the first eight; more decompositions exist.
