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.
