Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739928, here are decompositions:

11 + 8739917 = 8739928
17 + 8739911 = 8739928
59 + 8739869 = 8739928
101 + 8739827 = 8739928
107 + 8739821 = 8739928
179 + 8739749 = 8739928
257 + 8739671 = 8739928
311 + 8739617 = 8739928

Showing the first eight; more decompositions exist.
