Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598038, here are decompositions:

5 + 31598033 = 31598038
11 + 31598027 = 31598038
29 + 31598009 = 31598038
41 + 31597997 = 31598038
317 + 31597721 = 31598038
467 + 31597571 = 31598038
701 + 31597337 = 31598038
839 + 31597199 = 31598038

Showing the first eight; more decompositions exist.
