Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678494, here are decompositions:

47 + 8678447 = 8678494
101 + 8678393 = 8678494
131 + 8678363 = 8678494
257 + 8678237 = 8678494
281 + 8678213 = 8678494
347 + 8678147 = 8678494
353 + 8678141 = 8678494
401 + 8678093 = 8678494

Showing the first eight; more decompositions exist.
