Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51886, here are decompositions:
- 17 + 51869 = 51886
- 47 + 51839 = 51886
- 59 + 51827 = 51886
- 83 + 51803 = 51886
- 89 + 51797 = 51886
- 137 + 51749 = 51886
- 167 + 51719 = 51886
- 173 + 51713 = 51886
Showing the first eight; more decompositions exist.
