Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739968, here are decompositions:

7 + 8739961 = 8739968
31 + 8739937 = 8739968
67 + 8739901 = 8739968
157 + 8739811 = 8739968
199 + 8739769 = 8739968
229 + 8739739 = 8739968
331 + 8739637 = 8739968
439 + 8739529 = 8739968

Showing the first eight; more decompositions exist.
