Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559706, here are decompositions:

7 + 31559699 = 31559706
19 + 31559687 = 31559706
29 + 31559677 = 31559706
47 + 31559659 = 31559706
53 + 31559653 = 31559706
67 + 31559639 = 31559706
83 + 31559623 = 31559706
239 + 31559467 = 31559706

Showing the first eight; more decompositions exist.
