Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529052, here are decompositions:

59 + 31528993 = 31529052
83 + 31528969 = 31529052
199 + 31528853 = 31529052
211 + 31528841 = 31529052
229 + 31528823 = 31529052
239 + 31528813 = 31529052
241 + 31528811 = 31529052
251 + 31528801 = 31529052

Showing the first eight; more decompositions exist.
