Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565094, here are decompositions:

7 + 31565087 = 31565094
17 + 31565077 = 31565094
37 + 31565057 = 31565094
47 + 31565047 = 31565094
53 + 31565041 = 31565094
103 + 31564991 = 31565094
151 + 31564943 = 31565094
167 + 31564927 = 31565094

Showing the first eight; more decompositions exist.
