Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71066, here are decompositions:
- 7 + 71059 = 71066
- 43 + 71023 = 71066
- 67 + 70999 = 71066
- 97 + 70969 = 71066
- 109 + 70957 = 71066
- 199 + 70867 = 71066
- 223 + 70843 = 71066
- 283 + 70783 = 71066
Showing the first eight; more decompositions exist.
