Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513832, here are decompositions:
- 3 + 513829 = 513832
- 71 + 513761 = 513832
- 83 + 513749 = 513832
- 101 + 513731 = 513832
- 113 + 513719 = 513832
- 149 + 513683 = 513832
- 191 + 513641 = 513832
- 239 + 513593 = 513832
Showing the first eight; more decompositions exist.
