Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15028, here are decompositions:
- 11 + 15017 = 15028
- 59 + 14969 = 15028
- 71 + 14957 = 15028
- 89 + 14939 = 15028
- 131 + 14897 = 15028
- 137 + 14891 = 15028
- 149 + 14879 = 15028
- 197 + 14831 = 15028
Showing the first eight; more decompositions exist.
