Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678470, here are decompositions:

23 + 8678447 = 8678470
71 + 8678399 = 8678470
107 + 8678363 = 8678470
131 + 8678339 = 8678470
137 + 8678333 = 8678470
233 + 8678237 = 8678470
257 + 8678213 = 8678470
389 + 8678081 = 8678470

Showing the first eight; more decompositions exist.
