Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23420, here are decompositions:
- 3 + 23417 = 23420
- 109 + 23311 = 23420
- 127 + 23293 = 23420
- 151 + 23269 = 23420
- 193 + 23227 = 23420
- 211 + 23209 = 23420
- 223 + 23197 = 23420
- 277 + 23143 = 23420
Showing the first eight; more decompositions exist.
