Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535994, here are decompositions:

11 + 31535983 = 31535994
13 + 31535981 = 31535994
47 + 31535947 = 31535994
53 + 31535941 = 31535994
163 + 31535831 = 31535994
167 + 31535827 = 31535994
173 + 31535821 = 31535994
197 + 31535797 = 31535994

Showing the first eight; more decompositions exist.
