Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47040, here are decompositions:
- 23 + 47017 = 47040
- 43 + 46997 = 47040
- 47 + 46993 = 47040
- 83 + 46957 = 47040
- 107 + 46933 = 47040
- 139 + 46901 = 47040
- 151 + 46889 = 47040
- 163 + 46877 = 47040
Showing the first eight; more decompositions exist.
