Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21174, here are decompositions:
- 5 + 21169 = 21174
- 11 + 21163 = 21174
- 17 + 21157 = 21174
- 31 + 21143 = 21174
- 53 + 21121 = 21174
- 67 + 21107 = 21174
- 73 + 21101 = 21174
- 107 + 21067 = 21174
Showing the first eight; more decompositions exist.
