Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641368, here are decompositions:

7 + 8641361 = 8641368
17 + 8641351 = 8641368
19 + 8641349 = 8641368
37 + 8641331 = 8641368
41 + 8641327 = 8641368
59 + 8641309 = 8641368
67 + 8641301 = 8641368
79 + 8641289 = 8641368

Showing the first eight; more decompositions exist.
