Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598782, here are decompositions:

3 + 31598779 = 31598782
11 + 31598771 = 31598782
29 + 31598753 = 31598782
113 + 31598669 = 31598782
191 + 31598591 = 31598782
239 + 31598543 = 31598782
263 + 31598519 = 31598782
269 + 31598513 = 31598782

Showing the first eight; more decompositions exist.
