Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65816, here are decompositions:
- 7 + 65809 = 65816
- 97 + 65719 = 65816
- 103 + 65713 = 65816
- 109 + 65707 = 65816
- 139 + 65677 = 65816
- 199 + 65617 = 65816
- 229 + 65587 = 65816
- 277 + 65539 = 65816
Showing the first eight; more decompositions exist.
