Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567734, here are decompositions:

5 + 31567729 = 31567734
17 + 31567717 = 31567734
41 + 31567693 = 31567734
47 + 31567687 = 31567734
53 + 31567681 = 31567734
61 + 31567673 = 31567734
97 + 31567637 = 31567734
113 + 31567621 = 31567734

Showing the first eight; more decompositions exist.
