Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13098, here are decompositions:

5 + 13093 = 13098
61 + 13037 = 13098
89 + 13009 = 13098
97 + 13001 = 13098
131 + 12967 = 13098
139 + 12959 = 13098
157 + 12941 = 13098
179 + 12919 = 13098

Showing the first eight; more decompositions exist.
