Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564932, here are decompositions:

5 + 31564927 = 31564932
11 + 31564921 = 31564932
13 + 31564919 = 31564932
41 + 31564891 = 31564932
53 + 31564879 = 31564932
59 + 31564873 = 31564932
79 + 31564853 = 31564932
83 + 31564849 = 31564932

Showing the first eight; more decompositions exist.
