Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23220, here are decompositions:
- 11 + 23209 = 23220
- 17 + 23203 = 23220
- 19 + 23201 = 23220
- 23 + 23197 = 23220
- 31 + 23189 = 23220
- 47 + 23173 = 23220
- 53 + 23167 = 23220
- 61 + 23159 = 23220
Showing the first eight; more decompositions exist.
