Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547944, here are decompositions:

11 + 31547933 = 31547944
23 + 31547921 = 31547944
83 + 31547861 = 31547944
107 + 31547837 = 31547944
251 + 31547693 = 31547944
353 + 31547591 = 31547944
503 + 31547441 = 31547944
587 + 31547357 = 31547944

Showing the first eight; more decompositions exist.
