Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739986, here are decompositions:

19 + 8739967 = 8739986
67 + 8739919 = 8739986
103 + 8739883 = 8739986
109 + 8739877 = 8739986
163 + 8739823 = 8739986
313 + 8739673 = 8739986
349 + 8739637 = 8739986
379 + 8739607 = 8739986

Showing the first eight; more decompositions exist.
