Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547724, here are decompositions:

17 + 31547707 = 31547724
23 + 31547701 = 31547724
31 + 31547693 = 31547724
41 + 31547683 = 31547724
53 + 31547671 = 31547724
83 + 31547641 = 31547724
107 + 31547617 = 31547724
167 + 31547557 = 31547724

Showing the first eight; more decompositions exist.
