Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534962, here are decompositions:

83 + 31534879 = 31534962
89 + 31534873 = 31534962
131 + 31534831 = 31534962
163 + 31534799 = 31534962
211 + 31534751 = 31534962
223 + 31534739 = 31534962
233 + 31534729 = 31534962
271 + 31534691 = 31534962

Showing the first eight; more decompositions exist.
