Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66984, here are decompositions:
- 7 + 66977 = 66984
- 11 + 66973 = 66984
- 37 + 66947 = 66984
- 41 + 66943 = 66984
- 53 + 66931 = 66984
- 61 + 66923 = 66984
- 101 + 66883 = 66984
- 107 + 66877 = 66984
Showing the first eight; more decompositions exist.
