Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649994, here are decompositions:

83 + 8649911 = 8649994
107 + 8649887 = 8649994
113 + 8649881 = 8649994
137 + 8649857 = 8649994
191 + 8649803 = 8649994
233 + 8649761 = 8649994
317 + 8649677 = 8649994
383 + 8649611 = 8649994

Showing the first eight; more decompositions exist.
