Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567766, here are decompositions:

37 + 31567729 = 31567766
67 + 31567699 = 31567766
73 + 31567693 = 31567766
79 + 31567687 = 31567766
163 + 31567603 = 31567766
337 + 31567429 = 31567766
397 + 31567369 = 31567766
487 + 31567279 = 31567766

Showing the first eight; more decompositions exist.
