Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51982, here are decompositions:
- 5 + 51977 = 51982
- 11 + 51971 = 51982
- 41 + 51941 = 51982
- 53 + 51929 = 51982
- 83 + 51899 = 51982
- 89 + 51893 = 51982
- 113 + 51869 = 51982
- 179 + 51803 = 51982
Showing the first eight; more decompositions exist.
