Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13250, here are decompositions:
- 31 + 13219 = 13250
- 67 + 13183 = 13250
- 73 + 13177 = 13250
- 79 + 13171 = 13250
- 103 + 13147 = 13250
- 151 + 13099 = 13250
- 157 + 13093 = 13250
- 241 + 13009 = 13250
Showing the first eight; more decompositions exist.
