Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51936, here are decompositions:
- 7 + 51929 = 51936
- 23 + 51913 = 51936
- 29 + 51907 = 51936
- 37 + 51899 = 51936
- 43 + 51893 = 51936
- 67 + 51869 = 51936
- 83 + 51853 = 51936
- 97 + 51839 = 51936
Showing the first eight; more decompositions exist.
