Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13284, here are decompositions:
- 17 + 13267 = 13284
- 43 + 13241 = 13284
- 67 + 13217 = 13284
- 97 + 13187 = 13284
- 101 + 13183 = 13284
- 107 + 13177 = 13284
- 113 + 13171 = 13284
- 137 + 13147 = 13284
Showing the first eight; more decompositions exist.
