Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678584, here are decompositions:

3 + 8678581 = 8678584
137 + 8678447 = 8678584
191 + 8678393 = 8678584
251 + 8678333 = 8678584
347 + 8678237 = 8678584
443 + 8678141 = 8678584
491 + 8678093 = 8678584
503 + 8678081 = 8678584

Showing the first eight; more decompositions exist.
