Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690678, here are decompositions:

19 + 8690659 = 8690678
67 + 8690611 = 8690678
79 + 8690599 = 8690678
127 + 8690551 = 8690678
307 + 8690371 = 8690678
457 + 8690221 = 8690678
487 + 8690191 = 8690678
691 + 8689987 = 8690678

Showing the first eight; more decompositions exist.
