Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649364, here are decompositions:

11 + 8649353 = 8649364
41 + 8649323 = 8649364
47 + 8649317 = 8649364
71 + 8649293 = 8649364
137 + 8649227 = 8649364
167 + 8649197 = 8649364
173 + 8649191 = 8649364
293 + 8649071 = 8649364

Showing the first eight; more decompositions exist.
