Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13224, here are decompositions:
- 5 + 13219 = 13224
- 7 + 13217 = 13224
- 37 + 13187 = 13224
- 41 + 13183 = 13224
- 47 + 13177 = 13224
- 53 + 13171 = 13224
- 61 + 13163 = 13224
- 73 + 13151 = 13224
Showing the first eight; more decompositions exist.
