Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565046, here are decompositions:

5 + 31565041 = 31565046
17 + 31565029 = 31565046
67 + 31564979 = 31565046
103 + 31564943 = 31565046
113 + 31564933 = 31565046
127 + 31564919 = 31565046
167 + 31564879 = 31565046
173 + 31564873 = 31565046

Showing the first eight; more decompositions exist.
