Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15748, here are decompositions:
- 11 + 15737 = 15748
- 17 + 15731 = 15748
- 101 + 15647 = 15748
- 107 + 15641 = 15748
- 167 + 15581 = 15748
- 179 + 15569 = 15748
- 197 + 15551 = 15748
- 251 + 15497 = 15748
Showing the first eight; more decompositions exist.
