Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30006, here are decompositions:
- 17 + 29989 = 30006
- 23 + 29983 = 30006
- 47 + 29959 = 30006
- 59 + 29947 = 30006
- 79 + 29927 = 30006
- 89 + 29917 = 30006
- 127 + 29879 = 30006
- 139 + 29867 = 30006
Showing the first eight; more decompositions exist.
