Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20298, here are decompositions:
- 11 + 20287 = 20298
- 29 + 20269 = 20298
- 37 + 20261 = 20298
- 67 + 20231 = 20298
- 79 + 20219 = 20298
- 97 + 20201 = 20298
- 137 + 20161 = 20298
- 149 + 20149 = 20298
Showing the first eight; more decompositions exist.
