Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637566, here are decompositions:

43 + 8637523 = 8637566
73 + 8637493 = 8637566
139 + 8637427 = 8637566
193 + 8637373 = 8637566
229 + 8637337 = 8637566
277 + 8637289 = 8637566
313 + 8637253 = 8637566
433 + 8637133 = 8637566

Showing the first eight; more decompositions exist.
