Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15250, here are decompositions:
- 17 + 15233 = 15250
- 23 + 15227 = 15250
- 89 + 15161 = 15250
- 101 + 15149 = 15250
- 113 + 15137 = 15250
- 149 + 15101 = 15250
- 167 + 15083 = 15250
- 173 + 15077 = 15250
Showing the first eight; more decompositions exist.
