Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614962, here are decompositions:

19 + 31614943 = 31614962
73 + 31614889 = 31614962
103 + 31614859 = 31614962
109 + 31614853 = 31614962
193 + 31614769 = 31614962
229 + 31614733 = 31614962
331 + 31614631 = 31614962
439 + 31614523 = 31614962

Showing the first eight; more decompositions exist.
