Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539696, here are decompositions:

37 + 31539659 = 31539696
47 + 31539649 = 31539696
53 + 31539643 = 31539696
103 + 31539593 = 31539696
109 + 31539587 = 31539696
113 + 31539583 = 31539696
127 + 31539569 = 31539696
173 + 31539523 = 31539696

Showing the first eight; more decompositions exist.
