Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10202, here are decompositions:
- 43 + 10159 = 10202
- 61 + 10141 = 10202
- 103 + 10099 = 10202
- 109 + 10093 = 10202
- 163 + 10039 = 10202
- 193 + 10009 = 10202
- 229 + 9973 = 10202
- 271 + 9931 = 10202
Showing the first eight; more decompositions exist.
