Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529016, here are decompositions:

19 + 31528997 = 31529016
23 + 31528993 = 31529016
47 + 31528969 = 31529016
107 + 31528909 = 31529016
163 + 31528853 = 31529016
173 + 31528843 = 31529016
193 + 31528823 = 31529016
293 + 31528723 = 31529016

Showing the first eight; more decompositions exist.
