Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66018, here are decompositions:
- 37 + 65981 = 66018
- 61 + 65957 = 66018
- 67 + 65951 = 66018
- 89 + 65929 = 66018
- 97 + 65921 = 66018
- 137 + 65881 = 66018
- 151 + 65867 = 66018
- 167 + 65851 = 66018
Showing the first eight; more decompositions exist.
