Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29728, here are decompositions:
- 5 + 29723 = 29728
- 11 + 29717 = 29728
- 59 + 29669 = 29728
- 191 + 29537 = 29728
- 197 + 29531 = 29728
- 227 + 29501 = 29728
- 317 + 29411 = 29728
- 389 + 29339 = 29728
Showing the first eight; more decompositions exist.
