Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65978, here are decompositions:
- 79 + 65899 = 65978
- 97 + 65881 = 65978
- 127 + 65851 = 65978
- 139 + 65839 = 65978
- 151 + 65827 = 65978
- 271 + 65707 = 65978
- 277 + 65701 = 65978
- 331 + 65647 = 65978
Showing the first eight; more decompositions exist.
