Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529004, here are decompositions:

7 + 31528997 = 31529004
11 + 31528993 = 31529004
37 + 31528967 = 31529004
151 + 31528853 = 31529004
163 + 31528841 = 31529004
173 + 31528831 = 31529004
181 + 31528823 = 31529004
191 + 31528813 = 31529004

Showing the first eight; more decompositions exist.
