Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614150, here are decompositions:

17 + 31614133 = 31614150
41 + 31614109 = 31614150
53 + 31614097 = 31614150
59 + 31614091 = 31614150
79 + 31614071 = 31614150
89 + 31614061 = 31614150
131 + 31614019 = 31614150
149 + 31614001 = 31614150

Showing the first eight; more decompositions exist.
