Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598814, here are decompositions:

31 + 31598783 = 31598814
43 + 31598771 = 31598814
61 + 31598753 = 31598814
97 + 31598717 = 31598814
113 + 31598701 = 31598814
127 + 31598687 = 31598814
131 + 31598683 = 31598814
167 + 31598647 = 31598814

Showing the first eight; more decompositions exist.
