Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20244, here are decompositions:
- 11 + 20233 = 20244
- 13 + 20231 = 20244
- 43 + 20201 = 20244
- 61 + 20183 = 20244
- 67 + 20177 = 20244
- 71 + 20173 = 20244
- 83 + 20161 = 20244
- 97 + 20147 = 20244
Showing the first eight; more decompositions exist.
