Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31382, here are decompositions:
- 3 + 31379 = 31382
- 61 + 31321 = 31382
- 151 + 31231 = 31382
- 163 + 31219 = 31382
- 193 + 31189 = 31382
- 199 + 31183 = 31382
- 223 + 31159 = 31382
- 229 + 31153 = 31382
Showing the first eight; more decompositions exist.
