Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678648, here are decompositions:

61 + 8678587 = 8678648
67 + 8678581 = 8678648
337 + 8678311 = 8678648
487 + 8678161 = 8678648
499 + 8678149 = 8678648
619 + 8678029 = 8678648
757 + 8677891 = 8678648
877 + 8677771 = 8678648

Showing the first eight; more decompositions exist.
