Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614228, here are decompositions:

11 + 31614217 = 31614228
17 + 31614211 = 31614228
29 + 31614199 = 31614228
31 + 31614197 = 31614228
47 + 31614181 = 31614228
67 + 31614161 = 31614228
131 + 31614097 = 31614228
137 + 31614091 = 31614228

Showing the first eight; more decompositions exist.
