Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15206, here are decompositions:
- 7 + 15199 = 15206
- 13 + 15193 = 15206
- 19 + 15187 = 15206
- 67 + 15139 = 15206
- 193 + 15013 = 15206
- 223 + 14983 = 15206
- 277 + 14929 = 15206
- 283 + 14923 = 15206
Showing the first eight; more decompositions exist.
