Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598874, here are decompositions:

7 + 31598867 = 31598874
11 + 31598863 = 31598874
17 + 31598857 = 31598874
103 + 31598771 = 31598874
157 + 31598717 = 31598874
173 + 31598701 = 31598874
191 + 31598683 = 31598874
227 + 31598647 = 31598874

Showing the first eight; more decompositions exist.
