Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564602, here are decompositions:

11 + 31564591 = 31564602
71 + 31564531 = 31564602
101 + 31564501 = 31564602
163 + 31564439 = 31564602
211 + 31564391 = 31564602
241 + 31564361 = 31564602
269 + 31564333 = 31564602
271 + 31564331 = 31564602

Showing the first eight; more decompositions exist.
