Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547966, here are decompositions:

7 + 31547959 = 31547966
13 + 31547953 = 31547966
127 + 31547839 = 31547966
283 + 31547683 = 31547966
337 + 31547629 = 31547966
349 + 31547617 = 31547966
409 + 31547557 = 31547966
487 + 31547479 = 31547966

Showing the first eight; more decompositions exist.
