Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590696, here are decompositions:

13 + 31590683 = 31590696
29 + 31590667 = 31590696
37 + 31590659 = 31590696
47 + 31590649 = 31590696
79 + 31590617 = 31590696
103 + 31590593 = 31590696
107 + 31590589 = 31590696
113 + 31590583 = 31590696

Showing the first eight; more decompositions exist.
