Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547064, here are decompositions:

61 + 31547003 = 31547064
67 + 31546997 = 31547064
83 + 31546981 = 31547064
127 + 31546937 = 31547064
151 + 31546913 = 31547064
173 + 31546891 = 31547064
233 + 31546831 = 31547064
251 + 31546813 = 31547064

Showing the first eight; more decompositions exist.
