Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647698, here are decompositions:

41 + 8647657 = 8647698
109 + 8647589 = 8647698
131 + 8647567 = 8647698
167 + 8647531 = 8647698
197 + 8647501 = 8647698
229 + 8647469 = 8647698
239 + 8647459 = 8647698
251 + 8647447 = 8647698

Showing the first eight; more decompositions exist.
