Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21674, here are decompositions:
- 13 + 21661 = 21674
- 61 + 21613 = 21674
- 73 + 21601 = 21674
- 97 + 21577 = 21674
- 151 + 21523 = 21674
- 157 + 21517 = 21674
- 181 + 21493 = 21674
- 193 + 21481 = 21674
Showing the first eight; more decompositions exist.
