Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678486, here are decompositions:

13 + 8678473 = 8678486
127 + 8678359 = 8678486
163 + 8678323 = 8678486
283 + 8678203 = 8678486
307 + 8678179 = 8678486
337 + 8678149 = 8678486
373 + 8678113 = 8678486
433 + 8678053 = 8678486

Showing the first eight; more decompositions exist.
