Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678430, here are decompositions:

31 + 8678399 = 8678430
37 + 8678393 = 8678430
67 + 8678363 = 8678430
71 + 8678359 = 8678430
97 + 8678333 = 8678430
107 + 8678323 = 8678430
193 + 8678237 = 8678430
227 + 8678203 = 8678430

Showing the first eight; more decompositions exist.
