Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19624, here are decompositions:
- 41 + 19583 = 19624
- 47 + 19577 = 19624
- 53 + 19571 = 19624
- 71 + 19553 = 19624
- 83 + 19541 = 19624
- 167 + 19457 = 19624
- 191 + 19433 = 19624
- 197 + 19427 = 19624
Showing the first eight; more decompositions exist.
