Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529006, here are decompositions:

13 + 31528993 = 31529006
37 + 31528969 = 31529006
97 + 31528909 = 31529006
163 + 31528843 = 31529006
193 + 31528813 = 31529006
199 + 31528807 = 31529006
277 + 31528729 = 31529006
283 + 31528723 = 31529006

Showing the first eight; more decompositions exist.
