Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567706, here are decompositions:

7 + 31567699 = 31567706
13 + 31567693 = 31567706
19 + 31567687 = 31567706
103 + 31567603 = 31567706
193 + 31567513 = 31567706
277 + 31567429 = 31567706
337 + 31567369 = 31567706
409 + 31567297 = 31567706

Showing the first eight; more decompositions exist.
