Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650040, here are decompositions:

13 + 8650027 = 8650040
37 + 8650003 = 8650040
67 + 8649973 = 8650040
73 + 8649967 = 8650040
103 + 8649937 = 8650040
193 + 8649847 = 8650040
277 + 8649763 = 8650040
283 + 8649757 = 8650040

Showing the first eight; more decompositions exist.
