Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980978, here are decompositions:

67 + 980911 = 980978
79 + 980899 = 980978
127 + 980851 = 980978
151 + 980827 = 980978
337 + 980641 = 980978
379 + 980599 = 980978
421 + 980557 = 980978
487 + 980491 = 980978

Showing the first eight; more decompositions exist.
