Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31268, here are decompositions:
- 19 + 31249 = 31268
- 31 + 31237 = 31268
- 37 + 31231 = 31268
- 79 + 31189 = 31268
- 109 + 31159 = 31268
- 199 + 31069 = 31268
- 229 + 31039 = 31268
- 331 + 30937 = 31268
Showing the first eight; more decompositions exist.
