Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513846, here are decompositions:
- 5 + 513841 = 513846
- 7 + 513839 = 513846
- 17 + 513829 = 513846
- 79 + 513767 = 513846
- 97 + 513749 = 513846
- 107 + 513739 = 513846
- 127 + 513719 = 513846
- 149 + 513697 = 513846
Showing the first eight; more decompositions exist.
