Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91098, here are decompositions:

17 + 91081 = 91098
19 + 91079 = 91098
79 + 91019 = 91098
89 + 91009 = 91098
101 + 90997 = 91098
109 + 90989 = 91098
127 + 90971 = 91098
151 + 90947 = 91098

Showing the first eight; more decompositions exist.
