Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13450, here are decompositions:
- 29 + 13421 = 13450
- 53 + 13397 = 13450
- 83 + 13367 = 13450
- 113 + 13337 = 13450
- 137 + 13313 = 13450
- 191 + 13259 = 13450
- 233 + 13217 = 13450
- 263 + 13187 = 13450
Showing the first eight; more decompositions exist.
