Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29778, here are decompositions:
- 17 + 29761 = 29778
- 19 + 29759 = 29778
- 37 + 29741 = 29778
- 61 + 29717 = 29778
- 107 + 29671 = 29778
- 109 + 29669 = 29778
- 137 + 29641 = 29778
- 149 + 29629 = 29778
Showing the first eight; more decompositions exist.
