Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614864, here are decompositions:

5 + 31614859 = 31614864
11 + 31614853 = 31614864
13 + 31614851 = 31614864
31 + 31614833 = 31614864
67 + 31614797 = 31614864
131 + 31614733 = 31614864
157 + 31614707 = 31614864
163 + 31614701 = 31614864

Showing the first eight; more decompositions exist.
