Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90098, here are decompositions:

31 + 90067 = 90098
67 + 90031 = 90098
79 + 90019 = 90098
97 + 90001 = 90098
109 + 89989 = 90098
139 + 89959 = 90098
181 + 89917 = 90098
199 + 89899 = 90098

Showing the first eight; more decompositions exist.
