Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529082, here are decompositions:

29 + 31529053 = 31529082
89 + 31528993 = 31529082
113 + 31528969 = 31529082
173 + 31528909 = 31529082
229 + 31528853 = 31529082
239 + 31528843 = 31529082
241 + 31528841 = 31529082
251 + 31528831 = 31529082

Showing the first eight; more decompositions exist.
