Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670672, here are decompositions:

5 + 8670667 = 8670672
19 + 8670653 = 8670672
53 + 8670619 = 8670672
61 + 8670611 = 8670672
83 + 8670589 = 8670672
89 + 8670583 = 8670672
113 + 8670559 = 8670672
139 + 8670533 = 8670672

Showing the first eight; more decompositions exist.
