Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21294, here are decompositions:
- 11 + 21283 = 21294
- 17 + 21277 = 21294
- 47 + 21247 = 21294
- 67 + 21227 = 21294
- 73 + 21221 = 21294
- 83 + 21211 = 21294
- 101 + 21193 = 21294
- 103 + 21191 = 21294
Showing the first eight; more decompositions exist.
