Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40240, here are decompositions:

3 + 40237 = 40240
47 + 40193 = 40240
71 + 40169 = 40240
89 + 40151 = 40240
113 + 40127 = 40240
227 + 40013 = 40240
251 + 39989 = 40240
257 + 39983 = 40240

Showing the first eight; more decompositions exist.
