Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31966, here are decompositions:
- 3 + 31963 = 31966
- 59 + 31907 = 31966
- 83 + 31883 = 31966
- 107 + 31859 = 31966
- 149 + 31817 = 31966
- 167 + 31799 = 31966
- 173 + 31793 = 31966
- 197 + 31769 = 31966
Showing the first eight; more decompositions exist.
