Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678586, here are decompositions:

5 + 8678581 = 8678586
29 + 8678557 = 8678586
67 + 8678519 = 8678586
79 + 8678507 = 8678586
113 + 8678473 = 8678586
139 + 8678447 = 8678586
193 + 8678393 = 8678586
223 + 8678363 = 8678586

Showing the first eight; more decompositions exist.
