Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 982978, here are decompositions:

5 + 982973 = 982978
11 + 982967 = 982978
47 + 982931 = 982978
107 + 982871 = 982978
131 + 982847 = 982978
137 + 982841 = 982978
149 + 982829 = 982978
281 + 982697 = 982978

Showing the first eight; more decompositions exist.
