Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547006, here are decompositions:

3 + 31547003 = 31547006
19 + 31546987 = 31547006
37 + 31546969 = 31547006
97 + 31546909 = 31547006
163 + 31546843 = 31547006
193 + 31546813 = 31547006
199 + 31546807 = 31547006
349 + 31546657 = 31547006

Showing the first eight; more decompositions exist.
