Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739512, here are decompositions:

13 + 8739499 = 8739512
31 + 8739481 = 8739512
79 + 8739433 = 8739512
163 + 8739349 = 8739512
181 + 8739331 = 8739512
349 + 8739163 = 8739512
433 + 8739079 = 8739512
631 + 8738881 = 8739512

Showing the first eight; more decompositions exist.
