Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647740, here are decompositions:

29 + 8647711 = 8647740
41 + 8647699 = 8647740
43 + 8647697 = 8647740
83 + 8647657 = 8647740
151 + 8647589 = 8647740
173 + 8647567 = 8647740
229 + 8647511 = 8647740
239 + 8647501 = 8647740

Showing the first eight; more decompositions exist.
