Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535964, here are decompositions:

17 + 31535947 = 31535964
23 + 31535941 = 31535964
137 + 31535827 = 31535964
167 + 31535797 = 31535964
211 + 31535753 = 31535964
223 + 31535741 = 31535964
283 + 31535681 = 31535964
293 + 31535671 = 31535964

Showing the first eight; more decompositions exist.
