Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670684, here are decompositions:

5 + 8670679 = 8670684
17 + 8670667 = 8670684
31 + 8670653 = 8670684
47 + 8670637 = 8670684
73 + 8670611 = 8670684
101 + 8670583 = 8670684
131 + 8670553 = 8670684
151 + 8670533 = 8670684

Showing the first eight; more decompositions exist.
