Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7242, here are decompositions:
- 5 + 7237 = 7242
- 13 + 7229 = 7242
- 23 + 7219 = 7242
- 29 + 7213 = 7242
- 31 + 7211 = 7242
- 83 + 7159 = 7242
- 113 + 7129 = 7242
- 139 + 7103 = 7242
Showing the first eight; more decompositions exist.
