Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644674, here are decompositions:

13 + 8644661 = 8644674
23 + 8644651 = 8644674
41 + 8644633 = 8644674
67 + 8644607 = 8644674
163 + 8644511 = 8644674
167 + 8644507 = 8644674
173 + 8644501 = 8644674
197 + 8644477 = 8644674

Showing the first eight; more decompositions exist.
