Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13206, here are decompositions:
- 19 + 13187 = 13206
- 23 + 13183 = 13206
- 29 + 13177 = 13206
- 43 + 13163 = 13206
- 47 + 13159 = 13206
- 59 + 13147 = 13206
- 79 + 13127 = 13206
- 97 + 13109 = 13206
Showing the first eight; more decompositions exist.
