Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40342, here are decompositions:

53 + 40289 = 40342
59 + 40283 = 40342
89 + 40253 = 40342
101 + 40241 = 40342
149 + 40193 = 40342
173 + 40169 = 40342
179 + 40163 = 40342
191 + 40151 = 40342

Showing the first eight; more decompositions exist.
