Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620248, here are decompositions:

17 + 8620231 = 8620248
29 + 8620219 = 8620248
31 + 8620217 = 8620248
37 + 8620211 = 8620248
59 + 8620189 = 8620248
61 + 8620187 = 8620248
89 + 8620159 = 8620248
97 + 8620151 = 8620248

Showing the first eight; more decompositions exist.
