Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57920, here are decompositions:
- 3 + 57917 = 57920
- 19 + 57901 = 57920
- 61 + 57859 = 57920
- 67 + 57853 = 57920
- 73 + 57847 = 57920
- 127 + 57793 = 57920
- 139 + 57781 = 57920
- 193 + 57727 = 57920
Showing the first eight; more decompositions exist.
