Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678384, here are decompositions:

31 + 8678353 = 8678384
61 + 8678323 = 8678384
73 + 8678311 = 8678384
181 + 8678203 = 8678384
223 + 8678161 = 8678384
271 + 8678113 = 8678384
331 + 8678053 = 8678384
373 + 8678011 = 8678384

Showing the first eight; more decompositions exist.
