Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468564, here are decompositions:

5 + 31468559 = 31468564
11 + 31468553 = 31468564
41 + 31468523 = 31468564
47 + 31468517 = 31468564
53 + 31468511 = 31468564
167 + 31468397 = 31468564
173 + 31468391 = 31468564
227 + 31468337 = 31468564

Showing the first eight; more decompositions exist.
