Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461970, here are decompositions:
- 47 + 31461923 = 31461970
- 83 + 31461887 = 31461970
- 179 + 31461791 = 31461970
- 191 + 31461779 = 31461970
- 227 + 31461743 = 31461970
- 233 + 31461737 = 31461970
- 317 + 31461653 = 31461970
- 401 + 31461569 = 31461970
Showing the first eight; more decompositions exist.
