Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645324, here are decompositions:

31 + 8645293 = 8645324
43 + 8645281 = 8645324
67 + 8645257 = 8645324
211 + 8645113 = 8645324
271 + 8645053 = 8645324
277 + 8645047 = 8645324
313 + 8645011 = 8645324
367 + 8644957 = 8645324

Showing the first eight; more decompositions exist.
