Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40216, here are decompositions:
- 3 + 40213 = 40216
- 23 + 40193 = 40216
- 47 + 40169 = 40216
- 53 + 40163 = 40216
- 89 + 40127 = 40216
- 179 + 40037 = 40216
- 227 + 39989 = 40216
- 233 + 39983 = 40216
Showing the first eight; more decompositions exist.
