Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565052, here are decompositions:

5 + 31565047 = 31565052
11 + 31565041 = 31565052
23 + 31565029 = 31565052
61 + 31564991 = 31565052
73 + 31564979 = 31565052
109 + 31564943 = 31565052
131 + 31564921 = 31565052
173 + 31564879 = 31565052

Showing the first eight; more decompositions exist.
