Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668040, here are decompositions:

61 + 8667979 = 8668040
67 + 8667973 = 8668040
79 + 8667961 = 8668040
109 + 8667931 = 8668040
127 + 8667913 = 8668040
193 + 8667847 = 8668040
211 + 8667829 = 8668040
307 + 8667733 = 8668040

Showing the first eight; more decompositions exist.
