Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20202, here are decompositions:
- 19 + 20183 = 20202
- 29 + 20173 = 20202
- 41 + 20161 = 20202
- 53 + 20149 = 20202
- 59 + 20143 = 20202
- 73 + 20129 = 20202
- 79 + 20123 = 20202
- 89 + 20113 = 20202
Showing the first eight; more decompositions exist.
