Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637386, here are decompositions:

7 + 8637379 = 8637386
13 + 8637373 = 8637386
67 + 8637319 = 8637386
97 + 8637289 = 8637386
139 + 8637247 = 8637386
223 + 8637163 = 8637386
283 + 8637103 = 8637386
379 + 8637007 = 8637386

Showing the first eight; more decompositions exist.
