Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644742, here are decompositions:

13 + 8644729 = 8644742
19 + 8644723 = 8644742
109 + 8644633 = 8644742
241 + 8644501 = 8644742
499 + 8644243 = 8644742
571 + 8644171 = 8644742
619 + 8644123 = 8644742
661 + 8644081 = 8644742

Showing the first eight; more decompositions exist.
