Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645562, here are decompositions:

19 + 8645543 = 8645562
71 + 8645491 = 8645562
113 + 8645449 = 8645562
131 + 8645431 = 8645562
181 + 8645381 = 8645562
269 + 8645293 = 8645562
281 + 8645281 = 8645562
293 + 8645269 = 8645562

Showing the first eight; more decompositions exist.
