Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529276, here are decompositions:

3 + 31529273 = 31529276
7 + 31529269 = 31529276
19 + 31529257 = 31529276
109 + 31529167 = 31529276
127 + 31529149 = 31529276
223 + 31529053 = 31529276
283 + 31528993 = 31529276
307 + 31528969 = 31529276

Showing the first eight; more decompositions exist.
