Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23438, here are decompositions:
- 7 + 23431 = 23438
- 67 + 23371 = 23438
- 127 + 23311 = 23438
- 211 + 23227 = 23438
- 229 + 23209 = 23438
- 241 + 23197 = 23438
- 271 + 23167 = 23438
- 307 + 23131 = 23438
Showing the first eight; more decompositions exist.
