Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40408, here are decompositions:

47 + 40361 = 40408
131 + 40277 = 40408
167 + 40241 = 40408
239 + 40169 = 40408
257 + 40151 = 40408
281 + 40127 = 40408
419 + 39989 = 40408
479 + 39929 = 40408

Showing the first eight; more decompositions exist.
