Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23240, here are decompositions:
- 13 + 23227 = 23240
- 31 + 23209 = 23240
- 37 + 23203 = 23240
- 43 + 23197 = 23240
- 67 + 23173 = 23240
- 73 + 23167 = 23240
- 97 + 23143 = 23240
- 109 + 23131 = 23240
Showing the first eight; more decompositions exist.
