Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29808, here are decompositions:
- 5 + 29803 = 29808
- 19 + 29789 = 29808
- 47 + 29761 = 29808
- 67 + 29741 = 29808
- 137 + 29671 = 29808
- 139 + 29669 = 29808
- 167 + 29641 = 29808
- 179 + 29629 = 29808
Showing the first eight; more decompositions exist.
