Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678460, here are decompositions:

13 + 8678447 = 8678460
61 + 8678399 = 8678460
67 + 8678393 = 8678460
97 + 8678363 = 8678460
101 + 8678359 = 8678460
107 + 8678353 = 8678460
127 + 8678333 = 8678460
137 + 8678323 = 8678460

Showing the first eight; more decompositions exist.
