Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4202, here are decompositions:

43 + 4159 = 4202
73 + 4129 = 4202
103 + 4099 = 4202
109 + 4093 = 4202
151 + 4051 = 4202
181 + 4021 = 4202
199 + 4003 = 4202
271 + 3931 = 4202

Showing the first eight; more decompositions exist.
