Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5040, here are decompositions:
- 17 + 5023 = 5040
- 19 + 5021 = 5040
- 29 + 5011 = 5040
- 31 + 5009 = 5040
- 37 + 5003 = 5040
- 41 + 4999 = 5040
- 47 + 4993 = 5040
- 53 + 4987 = 5040
Showing the first eight; more decompositions exist.
