Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57870, here are decompositions:
- 11 + 57859 = 57870
- 17 + 57853 = 57870
- 23 + 57847 = 57870
- 31 + 57839 = 57870
- 41 + 57829 = 57870
- 61 + 57809 = 57870
- 67 + 57803 = 57870
- 79 + 57791 = 57870
Showing the first eight; more decompositions exist.
