Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529014, here are decompositions:

17 + 31528997 = 31529014
47 + 31528967 = 31529014
173 + 31528841 = 31529014
191 + 31528823 = 31529014
263 + 31528751 = 31529014
317 + 31528697 = 31529014
401 + 31528613 = 31529014
467 + 31528547 = 31529014

Showing the first eight; more decompositions exist.
