Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9098, here are decompositions:

7 + 9091 = 9098
31 + 9067 = 9098
97 + 9001 = 9098
127 + 8971 = 9098
157 + 8941 = 9098
211 + 8887 = 9098
277 + 8821 = 9098
337 + 8761 = 9098

Showing the first eight; more decompositions exist.
