Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65880, here are decompositions:
- 13 + 65867 = 65880
- 29 + 65851 = 65880
- 37 + 65843 = 65880
- 41 + 65839 = 65880
- 43 + 65837 = 65880
- 53 + 65827 = 65880
- 71 + 65809 = 65880
- 103 + 65777 = 65880
Showing the first eight; more decompositions exist.
