Also seen as
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.
