Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637684, here are decompositions:

17 + 8637667 = 8637684
43 + 8637641 = 8637684
47 + 8637637 = 8637684
67 + 8637617 = 8637684
73 + 8637611 = 8637684
157 + 8637527 = 8637684
163 + 8637521 = 8637684
191 + 8637493 = 8637684

Showing the first eight; more decompositions exist.
