Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614942, here are decompositions:

13 + 31614929 = 31614942
43 + 31614899 = 31614942
53 + 31614889 = 31614942
61 + 31614881 = 31614942
83 + 31614859 = 31614942
89 + 31614853 = 31614942
103 + 31614839 = 31614942
109 + 31614833 = 31614942

Showing the first eight; more decompositions exist.
