Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647390, here are decompositions:

23 + 8647367 = 8647390
41 + 8647349 = 8647390
113 + 8647277 = 8647390
137 + 8647253 = 8647390
197 + 8647193 = 8647390
233 + 8647157 = 8647390
251 + 8647139 = 8647390
263 + 8647127 = 8647390

Showing the first eight; more decompositions exist.
