Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142302, here are decompositions:

5 + 142297 = 142302
31 + 142271 = 142302
71 + 142231 = 142302
79 + 142223 = 142302
109 + 142193 = 142302
113 + 142189 = 142302
151 + 142151 = 142302
179 + 142123 = 142302

Showing the first eight; more decompositions exist.
