Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 202, here are decompositions:
- 3 + 199 = 202
- 5 + 197 = 202
- 11 + 191 = 202
- 23 + 179 = 202
- 29 + 173 = 202
- 53 + 149 = 202
- 71 + 131 = 202
- 89 + 113 = 202
Showing the first eight; more decompositions exist.
