Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66000, here are decompositions:
- 7 + 65993 = 66000
- 17 + 65983 = 66000
- 19 + 65981 = 66000
- 37 + 65963 = 66000
- 43 + 65957 = 66000
- 71 + 65929 = 66000
- 73 + 65927 = 66000
- 79 + 65921 = 66000
Showing the first eight; more decompositions exist.
