Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618080, here are decompositions:

17 + 8618063 = 8618080
47 + 8618033 = 8618080
59 + 8618021 = 8618080
89 + 8617991 = 8618080
131 + 8617949 = 8618080
137 + 8617943 = 8618080
257 + 8617823 = 8618080
281 + 8617799 = 8618080

Showing the first eight; more decompositions exist.
