Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670738, here are decompositions:

29 + 8670709 = 8670738
59 + 8670679 = 8670738
71 + 8670667 = 8670738
101 + 8670637 = 8670738
127 + 8670611 = 8670738
149 + 8670589 = 8670738
179 + 8670559 = 8670738
229 + 8670509 = 8670738

Showing the first eight; more decompositions exist.
