Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493114, here are decompositions:

31 + 31493083 = 31493114
61 + 31493053 = 31493114
67 + 31493047 = 31493114
97 + 31493017 = 31493114
151 + 31492963 = 31493114
181 + 31492933 = 31493114
193 + 31492921 = 31493114
277 + 31492837 = 31493114

Showing the first eight; more decompositions exist.
