Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80220, here are decompositions:

11 + 80209 = 80220
13 + 80207 = 80220
29 + 80191 = 80220
43 + 80177 = 80220
47 + 80173 = 80220
53 + 80167 = 80220
67 + 80153 = 80220
71 + 80149 = 80220

Showing the first eight; more decompositions exist.
