Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66064, here are decompositions:
- 17 + 66047 = 66064
- 23 + 66041 = 66064
- 71 + 65993 = 66064
- 83 + 65981 = 66064
- 101 + 65963 = 66064
- 107 + 65957 = 66064
- 113 + 65951 = 66064
- 137 + 65927 = 66064
Showing the first eight; more decompositions exist.
