Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494126, here are decompositions:

7 + 31494119 = 31494126
29 + 31494097 = 31494126
43 + 31494083 = 31494126
47 + 31494079 = 31494126
73 + 31494053 = 31494126
127 + 31493999 = 31494126
137 + 31493989 = 31494126
199 + 31493927 = 31494126

Showing the first eight; more decompositions exist.
