Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39240, here are decompositions:
- 7 + 39233 = 39240
- 11 + 39229 = 39240
- 13 + 39227 = 39240
- 23 + 39217 = 39240
- 31 + 39209 = 39240
- 41 + 39199 = 39240
- 59 + 39181 = 39240
- 79 + 39161 = 39240
Showing the first eight; more decompositions exist.
