Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564674, here are decompositions:

5 + 31564669 = 31564674
13 + 31564661 = 31564674
17 + 31564657 = 31564674
61 + 31564613 = 31564674
83 + 31564591 = 31564674
157 + 31564517 = 31564674
173 + 31564501 = 31564674
227 + 31564447 = 31564674

Showing the first eight; more decompositions exist.
