Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15000, here are decompositions:
- 17 + 14983 = 15000
- 31 + 14969 = 15000
- 43 + 14957 = 15000
- 53 + 14947 = 15000
- 61 + 14939 = 15000
- 71 + 14929 = 15000
- 103 + 14897 = 15000
- 109 + 14891 = 15000
Showing the first eight; more decompositions exist.
