Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102202, here are decompositions:

3 + 102199 = 102202
5 + 102197 = 102202
11 + 102191 = 102202
41 + 102161 = 102202
53 + 102149 = 102202
101 + 102101 = 102202
131 + 102071 = 102202
179 + 102023 = 102202

Showing the first eight; more decompositions exist.
