Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614138, here are decompositions:

5 + 31614133 = 31614138
29 + 31614109 = 31614138
41 + 31614097 = 31614138
47 + 31614091 = 31614138
67 + 31614071 = 31614138
131 + 31614007 = 31614138
137 + 31614001 = 31614138
211 + 31613927 = 31614138

Showing the first eight; more decompositions exist.
