Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739838, here are decompositions:

11 + 8739827 = 8739838
17 + 8739821 = 8739838
71 + 8739767 = 8739838
89 + 8739749 = 8739838
167 + 8739671 = 8739838
347 + 8739491 = 8739838
449 + 8739389 = 8739838
479 + 8739359 = 8739838

Showing the first eight; more decompositions exist.
