Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2202, here are decompositions:

23 + 2179 = 2202
41 + 2161 = 2202
59 + 2143 = 2202
61 + 2141 = 2202
71 + 2131 = 2202
73 + 2129 = 2202
89 + 2113 = 2202
103 + 2099 = 2202

Showing the first eight; more decompositions exist.
