Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15006, here are decompositions:
- 23 + 14983 = 15006
- 37 + 14969 = 15006
- 59 + 14947 = 15006
- 67 + 14939 = 15006
- 83 + 14923 = 15006
- 109 + 14897 = 15006
- 127 + 14879 = 15006
- 137 + 14869 = 15006
Showing the first eight; more decompositions exist.
