Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494036, here are decompositions:

37 + 31493999 = 31494036
47 + 31493989 = 31494036
53 + 31493983 = 31494036
109 + 31493927 = 31494036
127 + 31493909 = 31494036
137 + 31493899 = 31494036
179 + 31493857 = 31494036
257 + 31493779 = 31494036

Showing the first eight; more decompositions exist.
