Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580796, here are decompositions:

7 + 31580789 = 31580796
17 + 31580779 = 31580796
103 + 31580693 = 31580796
109 + 31580687 = 31580796
113 + 31580683 = 31580796
127 + 31580669 = 31580796
179 + 31580617 = 31580796
239 + 31580557 = 31580796

Showing the first eight; more decompositions exist.
