Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678420, here are decompositions:

61 + 8678359 = 8678420
67 + 8678353 = 8678420
97 + 8678323 = 8678420
109 + 8678311 = 8678420
241 + 8678179 = 8678420
271 + 8678149 = 8678420
307 + 8678113 = 8678420
337 + 8678083 = 8678420

Showing the first eight; more decompositions exist.
