Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51966, here are decompositions:
- 17 + 51949 = 51966
- 37 + 51929 = 51966
- 53 + 51913 = 51966
- 59 + 51907 = 51966
- 67 + 51899 = 51966
- 73 + 51893 = 51966
- 97 + 51869 = 51966
- 107 + 51859 = 51966
Showing the first eight; more decompositions exist.
