Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13200, here are decompositions:
- 13 + 13187 = 13200
- 17 + 13183 = 13200
- 23 + 13177 = 13200
- 29 + 13171 = 13200
- 37 + 13163 = 13200
- 41 + 13159 = 13200
- 53 + 13147 = 13200
- 73 + 13127 = 13200
Showing the first eight; more decompositions exist.
