Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567796, here are decompositions:

67 + 31567729 = 31567796
79 + 31567717 = 31567796
97 + 31567699 = 31567796
103 + 31567693 = 31567796
109 + 31567687 = 31567796
193 + 31567603 = 31567796
283 + 31567513 = 31567796
367 + 31567429 = 31567796

Showing the first eight; more decompositions exist.
