Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638706, here are decompositions:

19 + 8638687 = 8638706
73 + 8638633 = 8638706
79 + 8638627 = 8638706
163 + 8638543 = 8638706
229 + 8638477 = 8638706
367 + 8638339 = 8638706
379 + 8638327 = 8638706
487 + 8638219 = 8638706

Showing the first eight; more decompositions exist.
