Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27040, here are decompositions:
- 23 + 27017 = 27040
- 29 + 27011 = 27040
- 47 + 26993 = 27040
- 53 + 26987 = 27040
- 59 + 26981 = 27040
- 89 + 26951 = 27040
- 113 + 26927 = 27040
- 137 + 26903 = 27040
Showing the first eight; more decompositions exist.
