Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641102, here are decompositions:

5 + 8641097 = 8641102
23 + 8641079 = 8641102
191 + 8640911 = 8641102
383 + 8640719 = 8641102
389 + 8640713 = 8641102
401 + 8640701 = 8641102
419 + 8640683 = 8641102
599 + 8640503 = 8641102

Showing the first eight; more decompositions exist.
