Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66966, here are decompositions:
- 7 + 66959 = 66966
- 17 + 66949 = 66966
- 19 + 66947 = 66966
- 23 + 66943 = 66966
- 43 + 66923 = 66966
- 47 + 66919 = 66966
- 83 + 66883 = 66966
- 89 + 66877 = 66966
Showing the first eight; more decompositions exist.
