Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66040, here are decompositions:
- 3 + 66037 = 66040
- 11 + 66029 = 66040
- 47 + 65993 = 66040
- 59 + 65981 = 66040
- 83 + 65957 = 66040
- 89 + 65951 = 66040
- 113 + 65927 = 66040
- 173 + 65867 = 66040
Showing the first eight; more decompositions exist.
