Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15104, here are decompositions:
- 3 + 15101 = 15104
- 13 + 15091 = 15104
- 31 + 15073 = 15104
- 43 + 15061 = 15104
- 73 + 15031 = 15104
- 157 + 14947 = 15104
- 181 + 14923 = 15104
- 277 + 14827 = 15104
Showing the first eight; more decompositions exist.
