Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21324, here are decompositions:
- 5 + 21319 = 21324
- 7 + 21317 = 21324
- 11 + 21313 = 21324
- 41 + 21283 = 21324
- 47 + 21277 = 21324
- 97 + 21227 = 21324
- 103 + 21221 = 21324
- 113 + 21211 = 21324
Showing the first eight; more decompositions exist.
