Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739518, here are decompositions:

19 + 8739499 = 8739518
37 + 8739481 = 8739518
127 + 8739391 = 8739518
181 + 8739337 = 8739518
331 + 8739187 = 8739518
349 + 8739169 = 8739518
421 + 8739097 = 8739518
439 + 8739079 = 8739518

Showing the first eight; more decompositions exist.
