Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641846, here are decompositions:

29 + 8641817 = 8641846
113 + 8641733 = 8641846
137 + 8641709 = 8641846
149 + 8641697 = 8641846
173 + 8641673 = 8641846
233 + 8641613 = 8641846
557 + 8641289 = 8641846
599 + 8641247 = 8641846

Showing the first eight; more decompositions exist.
