Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30000, here are decompositions:
- 11 + 29989 = 30000
- 17 + 29983 = 30000
- 41 + 29959 = 30000
- 53 + 29947 = 30000
- 73 + 29927 = 30000
- 79 + 29921 = 30000
- 83 + 29917 = 30000
- 127 + 29873 = 30000
Showing the first eight; more decompositions exist.
