Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637356, here are decompositions:

19 + 8637337 = 8637356
37 + 8637319 = 8637356
67 + 8637289 = 8637356
103 + 8637253 = 8637356
109 + 8637247 = 8637356
193 + 8637163 = 8637356
223 + 8637133 = 8637356
349 + 8637007 = 8637356

Showing the first eight; more decompositions exist.
