Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494150, here are decompositions:

7 + 31494143 = 31494150
31 + 31494119 = 31494150
53 + 31494097 = 31494150
59 + 31494091 = 31494150
67 + 31494083 = 31494150
71 + 31494079 = 31494150
97 + 31494053 = 31494150
109 + 31494041 = 31494150

Showing the first eight; more decompositions exist.
