Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638746, here are decompositions:

13 + 8638733 = 8638746
19 + 8638727 = 8638746
59 + 8638687 = 8638746
113 + 8638633 = 8638746
163 + 8638583 = 8638746
229 + 8638517 = 8638746
269 + 8638477 = 8638746
283 + 8638463 = 8638746

Showing the first eight; more decompositions exist.
