Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980220, here are decompositions:

23 + 980197 = 980220
41 + 980179 = 980220
47 + 980173 = 980220
61 + 980159 = 980220
71 + 980149 = 980220
83 + 980137 = 980220
89 + 980131 = 980220
103 + 980117 = 980220

Showing the first eight; more decompositions exist.
