Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598796, here are decompositions:

7 + 31598789 = 31598796
13 + 31598783 = 31598796
17 + 31598779 = 31598796
43 + 31598753 = 31598796
79 + 31598717 = 31598796
109 + 31598687 = 31598796
113 + 31598683 = 31598796
127 + 31598669 = 31598796

Showing the first eight; more decompositions exist.
