Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30718, here are decompositions:
- 5 + 30713 = 30718
- 11 + 30707 = 30718
- 29 + 30689 = 30718
- 41 + 30677 = 30718
- 47 + 30671 = 30718
- 179 + 30539 = 30718
- 227 + 30491 = 30718
- 251 + 30467 = 30718
Showing the first eight; more decompositions exist.
