Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547950, here are decompositions:

17 + 31547933 = 31547950
29 + 31547921 = 31547950
89 + 31547861 = 31547950
101 + 31547849 = 31547950
113 + 31547837 = 31547950
167 + 31547783 = 31547950
257 + 31547693 = 31547950
359 + 31547591 = 31547950

Showing the first eight; more decompositions exist.
