Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529064, here are decompositions:

11 + 31529053 = 31529064
67 + 31528997 = 31529064
71 + 31528993 = 31529064
97 + 31528967 = 31529064
211 + 31528853 = 31529064
223 + 31528841 = 31529064
233 + 31528831 = 31529064
241 + 31528823 = 31529064

Showing the first eight; more decompositions exist.
