Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596678, here are decompositions:

5 + 31596673 = 31596678
7 + 31596671 = 31596678
17 + 31596661 = 31596678
41 + 31596637 = 31596678
67 + 31596611 = 31596678
107 + 31596571 = 31596678
137 + 31596541 = 31596678
167 + 31596511 = 31596678

Showing the first eight; more decompositions exist.
