Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23280, here are decompositions:
- 11 + 23269 = 23280
- 29 + 23251 = 23280
- 53 + 23227 = 23280
- 71 + 23209 = 23280
- 79 + 23201 = 23280
- 83 + 23197 = 23280
- 107 + 23173 = 23280
- 113 + 23167 = 23280
Showing the first eight; more decompositions exist.
