Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30726, here are decompositions:
- 13 + 30713 = 30726
- 19 + 30707 = 30726
- 23 + 30703 = 30726
- 29 + 30697 = 30726
- 37 + 30689 = 30726
- 83 + 30643 = 30726
- 89 + 30637 = 30726
- 149 + 30577 = 30726
Showing the first eight; more decompositions exist.
