Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31898, here are decompositions:

7 + 31891 = 31898
127 + 31771 = 31898
157 + 31741 = 31898
199 + 31699 = 31898
211 + 31687 = 31898
241 + 31657 = 31898
271 + 31627 = 31898
331 + 31567 = 31898

Showing the first eight; more decompositions exist.
