Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641002, here are decompositions:

53 + 8640949 = 8641002
113 + 8640889 = 8641002
131 + 8640871 = 8641002
179 + 8640823 = 8641002
241 + 8640761 = 8641002
263 + 8640739 = 8641002
269 + 8640733 = 8641002
283 + 8640719 = 8641002

Showing the first eight; more decompositions exist.
