Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758644, here are decompositions:

7 + 8758637 = 8758644
47 + 8758597 = 8758644
61 + 8758583 = 8758644
67 + 8758577 = 8758644
71 + 8758573 = 8758644
107 + 8758537 = 8758644
131 + 8758513 = 8758644
137 + 8758507 = 8758644

Showing the first eight; more decompositions exist.
