Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66960, here are decompositions:
- 11 + 66949 = 66960
- 13 + 66947 = 66960
- 17 + 66943 = 66960
- 29 + 66931 = 66960
- 37 + 66923 = 66960
- 41 + 66919 = 66960
- 71 + 66889 = 66960
- 83 + 66877 = 66960
Showing the first eight; more decompositions exist.
