Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743980, here are decompositions:

17 + 8743963 = 8743980
43 + 8743937 = 8743980
61 + 8743919 = 8743980
67 + 8743913 = 8743980
79 + 8743901 = 8743980
97 + 8743883 = 8743980
101 + 8743879 = 8743980
127 + 8743853 = 8743980

Showing the first eight; more decompositions exist.
