Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645340, here are decompositions:

13 + 8645327 = 8645340
47 + 8645293 = 8645340
59 + 8645281 = 8645340
71 + 8645269 = 8645340
73 + 8645267 = 8645340
79 + 8645261 = 8645340
83 + 8645257 = 8645340
97 + 8645243 = 8645340

Showing the first eight; more decompositions exist.
