Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30112, here are decompositions:
- 3 + 30109 = 30112
- 23 + 30089 = 30112
- 41 + 30071 = 30112
- 53 + 30059 = 30112
- 83 + 30029 = 30112
- 101 + 30011 = 30112
- 191 + 29921 = 30112
- 233 + 29879 = 30112
Showing the first eight; more decompositions exist.
