Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51858, here are decompositions:
- 5 + 51853 = 51858
- 19 + 51839 = 51858
- 29 + 51829 = 51858
- 31 + 51827 = 51858
- 41 + 51817 = 51858
- 61 + 51797 = 51858
- 71 + 51787 = 51858
- 89 + 51769 = 51858
Showing the first eight; more decompositions exist.
