Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649486, here are decompositions:

7 + 8649479 = 8649486
17 + 8649469 = 8649486
19 + 8649467 = 8649486
23 + 8649463 = 8649486
67 + 8649419 = 8649486
103 + 8649383 = 8649486
137 + 8649349 = 8649486
163 + 8649323 = 8649486

Showing the first eight; more decompositions exist.
