Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11040, here are decompositions:
- 13 + 11027 = 11040
- 37 + 11003 = 11040
- 47 + 10993 = 11040
- 53 + 10987 = 11040
- 61 + 10979 = 11040
- 67 + 10973 = 11040
- 83 + 10957 = 11040
- 101 + 10939 = 11040
Showing the first eight; more decompositions exist.
