Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31996, here are decompositions:
- 5 + 31991 = 31996
- 23 + 31973 = 31996
- 89 + 31907 = 31996
- 113 + 31883 = 31996
- 137 + 31859 = 31996
- 149 + 31847 = 31996
- 179 + 31817 = 31996
- 197 + 31799 = 31996
Showing the first eight; more decompositions exist.
