Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535950, here are decompositions:

3 + 31535947 = 31535950
11 + 31535939 = 31535950
41 + 31535909 = 31535950
71 + 31535879 = 31535950
197 + 31535753 = 31535950
233 + 31535717 = 31535950
269 + 31535681 = 31535950
293 + 31535657 = 31535950

Showing the first eight; more decompositions exist.
