Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537016, here are decompositions:

13 + 31537003 = 31537016
73 + 31536943 = 31537016
79 + 31536937 = 31537016
193 + 31536823 = 31537016
223 + 31536793 = 31537016
283 + 31536733 = 31537016
409 + 31536607 = 31537016
487 + 31536529 = 31537016

Showing the first eight; more decompositions exist.
