Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614918, here are decompositions:

19 + 31614899 = 31614918
29 + 31614889 = 31614918
37 + 31614881 = 31614918
59 + 31614859 = 31614918
67 + 31614851 = 31614918
79 + 31614839 = 31614918
89 + 31614829 = 31614918
131 + 31614787 = 31614918

Showing the first eight; more decompositions exist.
