Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513838, here are decompositions:
- 71 + 513767 = 513838
- 89 + 513749 = 513838
- 107 + 513731 = 513838
- 197 + 513641 = 513838
- 359 + 513479 = 513838
- 419 + 513419 = 513838
- 431 + 513407 = 513838
- 467 + 513371 = 513838
Showing the first eight; more decompositions exist.
