Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535938, here are decompositions:

29 + 31535909 = 31535938
59 + 31535879 = 31535938
107 + 31535831 = 31535938
191 + 31535747 = 31535938
197 + 31535741 = 31535938
257 + 31535681 = 31535938
281 + 31535657 = 31535938
347 + 31535591 = 31535938

Showing the first eight; more decompositions exist.
