Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565058, here are decompositions:

11 + 31565047 = 31565058
17 + 31565041 = 31565058
29 + 31565029 = 31565058
67 + 31564991 = 31565058
79 + 31564979 = 31565058
131 + 31564927 = 31565058
137 + 31564921 = 31565058
139 + 31564919 = 31565058

Showing the first eight; more decompositions exist.
