Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739868, here are decompositions:

17 + 8739851 = 8739868
41 + 8739827 = 8739868
47 + 8739821 = 8739868
101 + 8739767 = 8739868
197 + 8739671 = 8739868
251 + 8739617 = 8739868
479 + 8739389 = 8739868
509 + 8739359 = 8739868

Showing the first eight; more decompositions exist.
