Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647522, here are decompositions:

11 + 8647511 = 8647522
53 + 8647469 = 8647522
113 + 8647409 = 8647522
131 + 8647391 = 8647522
173 + 8647349 = 8647522
269 + 8647253 = 8647522
293 + 8647229 = 8647522
383 + 8647139 = 8647522

Showing the first eight; more decompositions exist.
