Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131298, here are decompositions:
- 5 + 131293 = 131298
- 31 + 131267 = 131298
- 47 + 131251 = 131298
- 67 + 131231 = 131298
- 127 + 131171 = 131298
- 149 + 131149 = 131298
- 197 + 131101 = 131298
- 227 + 131071 = 131298
Showing the first eight; more decompositions exist.
