Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31948, here are decompositions:
- 41 + 31907 = 31948
- 89 + 31859 = 31948
- 101 + 31847 = 31948
- 131 + 31817 = 31948
- 149 + 31799 = 31948
- 179 + 31769 = 31948
- 197 + 31751 = 31948
- 227 + 31721 = 31948
Showing the first eight; more decompositions exist.
