Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739870, here are decompositions:

19 + 8739851 = 8739870
43 + 8739827 = 8739870
47 + 8739823 = 8739870
59 + 8739811 = 8739870
67 + 8739803 = 8739870
101 + 8739769 = 8739870
103 + 8739767 = 8739870
131 + 8739739 = 8739870

Showing the first eight; more decompositions exist.
