Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20356, here are decompositions:
- 3 + 20353 = 20356
- 23 + 20333 = 20356
- 29 + 20327 = 20356
- 59 + 20297 = 20356
- 107 + 20249 = 20356
- 137 + 20219 = 20356
- 173 + 20183 = 20356
- 179 + 20177 = 20356
Showing the first eight; more decompositions exist.
