Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739782, here are decompositions:

13 + 8739769 = 8739782
43 + 8739739 = 8739782
61 + 8739721 = 8739782
109 + 8739673 = 8739782
199 + 8739583 = 8739782
283 + 8739499 = 8739782
349 + 8739433 = 8739782
433 + 8739349 = 8739782

Showing the first eight; more decompositions exist.
