Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529034, here are decompositions:

37 + 31528997 = 31529034
41 + 31528993 = 31529034
67 + 31528967 = 31529034
181 + 31528853 = 31529034
191 + 31528843 = 31529034
193 + 31528841 = 31529034
211 + 31528823 = 31529034
223 + 31528811 = 31529034

Showing the first eight; more decompositions exist.
