Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29680, here are decompositions:
- 11 + 29669 = 29680
- 17 + 29663 = 29680
- 47 + 29633 = 29680
- 107 + 29573 = 29680
- 113 + 29567 = 29680
- 149 + 29531 = 29680
- 179 + 29501 = 29680
- 197 + 29483 = 29680
Showing the first eight; more decompositions exist.
