Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13730, here are decompositions:
- 7 + 13723 = 13730
- 19 + 13711 = 13730
- 37 + 13693 = 13730
- 43 + 13687 = 13730
- 61 + 13669 = 13730
- 97 + 13633 = 13730
- 103 + 13627 = 13730
- 139 + 13591 = 13730
Showing the first eight; more decompositions exist.
