Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40340, here are decompositions:

103 + 40237 = 40340
109 + 40231 = 40340
127 + 40213 = 40340
151 + 40189 = 40340
163 + 40177 = 40340
211 + 40129 = 40340
229 + 40111 = 40340
241 + 40099 = 40340

Showing the first eight; more decompositions exist.
