Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649470, here are decompositions:

3 + 8649467 = 8649470
7 + 8649463 = 8649470
19 + 8649451 = 8649470
61 + 8649409 = 8649470
79 + 8649391 = 8649470
103 + 8649367 = 8649470
127 + 8649343 = 8649470
139 + 8649331 = 8649470

Showing the first eight; more decompositions exist.
