Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567746, here are decompositions:

5 + 31567741 = 31567746
17 + 31567729 = 31567746
29 + 31567717 = 31567746
37 + 31567709 = 31567746
47 + 31567699 = 31567746
53 + 31567693 = 31567746
59 + 31567687 = 31567746
73 + 31567673 = 31567746

Showing the first eight; more decompositions exist.
