Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547952, here are decompositions:

19 + 31547933 = 31547952
31 + 31547921 = 31547952
101 + 31547851 = 31547952
103 + 31547849 = 31547952
113 + 31547839 = 31547952
251 + 31547701 = 31547952
269 + 31547683 = 31547952
281 + 31547671 = 31547952

Showing the first eight; more decompositions exist.
