Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980988, here are decompositions:

31 + 980957 = 980988
67 + 980921 = 980988
79 + 980909 = 980988
89 + 980899 = 980988
101 + 980887 = 980988
137 + 980851 = 980988
157 + 980831 = 980988
257 + 980731 = 980988

Showing the first eight; more decompositions exist.
