Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678884, here are decompositions:

101 + 8678783 = 8678884
107 + 8678777 = 8678884
131 + 8678753 = 8678884
191 + 8678693 = 8678884
281 + 8678603 = 8678884
491 + 8678393 = 8678884
521 + 8678363 = 8678884
647 + 8678237 = 8678884

Showing the first eight; more decompositions exist.
