Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71948, here are decompositions:
- 7 + 71941 = 71948
- 31 + 71917 = 71948
- 61 + 71887 = 71948
- 67 + 71881 = 71948
- 127 + 71821 = 71948
- 139 + 71809 = 71948
- 229 + 71719 = 71948
- 241 + 71707 = 71948
Showing the first eight; more decompositions exist.
