Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13210, here are decompositions:
- 23 + 13187 = 13210
- 47 + 13163 = 13210
- 59 + 13151 = 13210
- 83 + 13127 = 13210
- 89 + 13121 = 13210
- 101 + 13109 = 13210
- 107 + 13103 = 13210
- 167 + 13043 = 13210
Showing the first eight; more decompositions exist.
