Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29988, here are decompositions:
- 5 + 29983 = 29988
- 29 + 29959 = 29988
- 41 + 29947 = 29988
- 61 + 29927 = 29988
- 67 + 29921 = 29988
- 71 + 29917 = 29988
- 107 + 29881 = 29988
- 109 + 29879 = 29988
Showing the first eight; more decompositions exist.
