Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7998, here are decompositions:
- 5 + 7993 = 7998
- 47 + 7951 = 7998
- 61 + 7937 = 7998
- 71 + 7927 = 7998
- 79 + 7919 = 7998
- 97 + 7901 = 7998
- 131 + 7867 = 7998
- 157 + 7841 = 7998
Showing the first eight; more decompositions exist.
