Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598766, here are decompositions:

13 + 31598753 = 31598766
79 + 31598687 = 31598766
83 + 31598683 = 31598766
97 + 31598669 = 31598766
223 + 31598543 = 31598766
229 + 31598537 = 31598766
307 + 31598459 = 31598766
317 + 31598449 = 31598766

Showing the first eight; more decompositions exist.
