Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21114, here are decompositions:
- 7 + 21107 = 21114
- 13 + 21101 = 21114
- 47 + 21067 = 21114
- 53 + 21061 = 21114
- 83 + 21031 = 21114
- 97 + 21017 = 21114
- 101 + 21013 = 21114
- 103 + 21011 = 21114
Showing the first eight; more decompositions exist.
