Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638594, here are decompositions:

11 + 8638583 = 8638594
113 + 8638481 = 8638594
131 + 8638463 = 8638594
137 + 8638457 = 8638594
191 + 8638403 = 8638594
257 + 8638337 = 8638594
311 + 8638283 = 8638594
317 + 8638277 = 8638594

Showing the first eight; more decompositions exist.
