Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678570, here are decompositions:

13 + 8678557 = 8678570
97 + 8678473 = 8678570
211 + 8678359 = 8678570
367 + 8678203 = 8678570
409 + 8678161 = 8678570
421 + 8678149 = 8678570
457 + 8678113 = 8678570
487 + 8678083 = 8678570

Showing the first eight; more decompositions exist.
