Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739984, here are decompositions:

17 + 8739967 = 8739984
23 + 8739961 = 8739984
31 + 8739953 = 8739984
47 + 8739937 = 8739984
67 + 8739917 = 8739984
73 + 8739911 = 8739984
83 + 8739901 = 8739984
101 + 8739883 = 8739984

Showing the first eight; more decompositions exist.
