Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515848, here are decompositions:
- 5 + 515843 = 515848
- 71 + 515777 = 515848
- 107 + 515741 = 515848
- 167 + 515681 = 515848
- 197 + 515651 = 515848
- 227 + 515621 = 515848
- 251 + 515597 = 515848
- 269 + 515579 = 515848
Showing the first eight; more decompositions exist.
