Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15048, here are decompositions:
- 17 + 15031 = 15048
- 31 + 15017 = 15048
- 79 + 14969 = 15048
- 97 + 14951 = 15048
- 101 + 14947 = 15048
- 109 + 14939 = 15048
- 151 + 14897 = 15048
- 157 + 14891 = 15048
Showing the first eight; more decompositions exist.
