Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5978, here are decompositions:
- 97 + 5881 = 5978
- 109 + 5869 = 5978
- 127 + 5851 = 5978
- 139 + 5839 = 5978
- 151 + 5827 = 5978
- 157 + 5821 = 5978
- 199 + 5779 = 5978
- 229 + 5749 = 5978
Showing the first eight; more decompositions exist.
