Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645360, here are decompositions:

7 + 8645353 = 8645360
19 + 8645341 = 8645360
67 + 8645293 = 8645360
79 + 8645281 = 8645360
103 + 8645257 = 8645360
181 + 8645179 = 8645360
307 + 8645053 = 8645360
313 + 8645047 = 8645360

Showing the first eight; more decompositions exist.
