Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565264, here are decompositions:

7 + 31565257 = 31565264
43 + 31565221 = 31565264
67 + 31565197 = 31565264
97 + 31565167 = 31565264
163 + 31565101 = 31565264
223 + 31565041 = 31565264
331 + 31564933 = 31565264
337 + 31564927 = 31565264

Showing the first eight; more decompositions exist.
