Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678540, here are decompositions:

67 + 8678473 = 8678540
181 + 8678359 = 8678540
229 + 8678311 = 8678540
337 + 8678203 = 8678540
379 + 8678161 = 8678540
457 + 8678083 = 8678540
487 + 8678053 = 8678540
547 + 8677993 = 8678540

Showing the first eight; more decompositions exist.
