Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730678, here are decompositions:

17 + 8730661 = 8730678
29 + 8730649 = 8730678
59 + 8730619 = 8730678
67 + 8730611 = 8730678
71 + 8730607 = 8730678
101 + 8730577 = 8730678
149 + 8730529 = 8730678
167 + 8730511 = 8730678

Showing the first eight; more decompositions exist.
