Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30212, here are decompositions:
- 31 + 30181 = 30212
- 43 + 30169 = 30212
- 73 + 30139 = 30212
- 79 + 30133 = 30212
- 103 + 30109 = 30212
- 109 + 30103 = 30212
- 199 + 30013 = 30212
- 223 + 29989 = 30212
Showing the first eight; more decompositions exist.
