Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564934, here are decompositions:

7 + 31564927 = 31564934
13 + 31564921 = 31564934
43 + 31564891 = 31564934
61 + 31564873 = 31564934
103 + 31564831 = 31564934
127 + 31564807 = 31564934
211 + 31564723 = 31564934
277 + 31564657 = 31564934

Showing the first eight; more decompositions exist.
