Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618470, here are decompositions:

41 + 8618429 = 8618470
83 + 8618387 = 8618470
131 + 8618339 = 8618470
173 + 8618297 = 8618470
197 + 8618273 = 8618470
227 + 8618243 = 8618470
233 + 8618237 = 8618470
257 + 8618213 = 8618470

Showing the first eight; more decompositions exist.
