Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19588, here are decompositions:
- 5 + 19583 = 19588
- 11 + 19577 = 19588
- 17 + 19571 = 19588
- 29 + 19559 = 19588
- 47 + 19541 = 19588
- 131 + 19457 = 19588
- 167 + 19421 = 19588
- 197 + 19391 = 19588
Showing the first eight; more decompositions exist.
