Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20202, here are decompositions:

19 + 20183 = 20202
29 + 20173 = 20202
41 + 20161 = 20202
53 + 20149 = 20202
59 + 20143 = 20202
73 + 20129 = 20202
79 + 20123 = 20202
89 + 20113 = 20202

Showing the first eight; more decompositions exist.
