Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40224, here are decompositions:
- 11 + 40213 = 40224
- 31 + 40193 = 40224
- 47 + 40177 = 40224
- 61 + 40163 = 40224
- 71 + 40153 = 40224
- 73 + 40151 = 40224
- 97 + 40127 = 40224
- 101 + 40123 = 40224
Showing the first eight; more decompositions exist.
