Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743668, here are decompositions:

29 + 8743639 = 8743668
47 + 8743621 = 8743668
71 + 8743597 = 8743668
79 + 8743589 = 8743668
97 + 8743571 = 8743668
107 + 8743561 = 8743668
137 + 8743531 = 8743668
179 + 8743489 = 8743668

Showing the first eight; more decompositions exist.
