Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649824, here are decompositions:

31 + 8649793 = 8649824
61 + 8649763 = 8649824
67 + 8649757 = 8649824
103 + 8649721 = 8649824
163 + 8649661 = 8649824
307 + 8649517 = 8649824
373 + 8649451 = 8649824
433 + 8649391 = 8649824

Showing the first eight; more decompositions exist.
