Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7040, here are decompositions:
- 13 + 7027 = 7040
- 43 + 6997 = 7040
- 73 + 6967 = 7040
- 79 + 6961 = 7040
- 157 + 6883 = 7040
- 199 + 6841 = 7040
- 211 + 6829 = 7040
- 277 + 6763 = 7040
Showing the first eight; more decompositions exist.
