Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15146, here are decompositions:
- 7 + 15139 = 15146
- 73 + 15073 = 15146
- 163 + 14983 = 15146
- 199 + 14947 = 15146
- 223 + 14923 = 15146
- 277 + 14869 = 15146
- 349 + 14797 = 15146
- 367 + 14779 = 15146
Showing the first eight; more decompositions exist.
