Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535956, here are decompositions:

17 + 31535939 = 31535956
47 + 31535909 = 31535956
239 + 31535717 = 31535956
317 + 31535639 = 31535956
743 + 31535213 = 31535956
773 + 31535183 = 31535956
1217 + 31534739 = 31535956
1319 + 31534637 = 31535956

Showing the first eight; more decompositions exist.
