Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739690, here are decompositions:

17 + 8739673 = 8739690
19 + 8739671 = 8739690
23 + 8739667 = 8739690
53 + 8739637 = 8739690
67 + 8739623 = 8739690
73 + 8739617 = 8739690
83 + 8739607 = 8739690
107 + 8739583 = 8739690

Showing the first eight; more decompositions exist.
