Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649794, here are decompositions:

3 + 8649791 = 8649794
31 + 8649763 = 8649794
37 + 8649757 = 8649794
73 + 8649721 = 8649794
103 + 8649691 = 8649794
157 + 8649637 = 8649794
277 + 8649517 = 8649794
331 + 8649463 = 8649794

Showing the first eight; more decompositions exist.
