Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15948, here are decompositions:
- 11 + 15937 = 15948
- 29 + 15919 = 15948
- 41 + 15907 = 15948
- 47 + 15901 = 15948
- 59 + 15889 = 15948
- 61 + 15887 = 15948
- 67 + 15881 = 15948
- 71 + 15877 = 15948
Showing the first eight; more decompositions exist.
