Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31316, here are decompositions:
- 67 + 31249 = 31316
- 79 + 31237 = 31316
- 97 + 31219 = 31316
- 127 + 31189 = 31316
- 139 + 31177 = 31316
- 157 + 31159 = 31316
- 163 + 31153 = 31316
- 193 + 31123 = 31316
Showing the first eight; more decompositions exist.
