Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21314, here are decompositions:
- 31 + 21283 = 21314
- 37 + 21277 = 21314
- 67 + 21247 = 21314
- 103 + 21211 = 21314
- 127 + 21187 = 21314
- 151 + 21163 = 21314
- 157 + 21157 = 21314
- 193 + 21121 = 21314
Showing the first eight; more decompositions exist.
