Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567698, here are decompositions:

5 + 31567693 = 31567698
11 + 31567687 = 31567698
17 + 31567681 = 31567698
61 + 31567637 = 31567698
79 + 31567619 = 31567698
139 + 31567559 = 31567698
269 + 31567429 = 31567698
271 + 31567427 = 31567698

Showing the first eight; more decompositions exist.
