Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66004, here are decompositions:
- 11 + 65993 = 66004
- 23 + 65981 = 66004
- 41 + 65963 = 66004
- 47 + 65957 = 66004
- 53 + 65951 = 66004
- 83 + 65921 = 66004
- 137 + 65867 = 66004
- 167 + 65837 = 66004
Showing the first eight; more decompositions exist.
