Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564682, here are decompositions:

13 + 31564669 = 31564682
43 + 31564639 = 31564682
151 + 31564531 = 31564682
181 + 31564501 = 31564682
223 + 31564459 = 31564682
349 + 31564333 = 31564682
421 + 31564261 = 31564682
433 + 31564249 = 31564682

Showing the first eight; more decompositions exist.
