Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739684, here are decompositions:

11 + 8739673 = 8739684
13 + 8739671 = 8739684
17 + 8739667 = 8739684
47 + 8739637 = 8739684
61 + 8739623 = 8739684
67 + 8739617 = 8739684
101 + 8739583 = 8739684
181 + 8739503 = 8739684

Showing the first eight; more decompositions exist.
