Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535914, here are decompositions:

5 + 31535909 = 31535914
83 + 31535831 = 31535914
167 + 31535747 = 31535914
173 + 31535741 = 31535914
197 + 31535717 = 31535914
233 + 31535681 = 31535914
257 + 31535657 = 31535914
281 + 31535633 = 31535914

Showing the first eight; more decompositions exist.
