Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678466, here are decompositions:

19 + 8678447 = 8678466
67 + 8678399 = 8678466
73 + 8678393 = 8678466
103 + 8678363 = 8678466
107 + 8678359 = 8678466
113 + 8678353 = 8678466
127 + 8678339 = 8678466
229 + 8678237 = 8678466

Showing the first eight; more decompositions exist.
