Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100342, here are decompositions:

29 + 100313 = 100342
71 + 100271 = 100342
149 + 100193 = 100342
173 + 100169 = 100342
191 + 100151 = 100342
233 + 100109 = 100342
239 + 100103 = 100342
293 + 100049 = 100342

Showing the first eight; more decompositions exist.
