Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65988, here are decompositions:
- 5 + 65983 = 65988
- 7 + 65981 = 65988
- 31 + 65957 = 65988
- 37 + 65951 = 65988
- 59 + 65929 = 65988
- 61 + 65927 = 65988
- 67 + 65921 = 65988
- 89 + 65899 = 65988
Showing the first eight; more decompositions exist.
