Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30198, here are decompositions:
- 11 + 30187 = 30198
- 17 + 30181 = 30198
- 29 + 30169 = 30198
- 37 + 30161 = 30198
- 59 + 30139 = 30198
- 61 + 30137 = 30198
- 79 + 30119 = 30198
- 89 + 30109 = 30198
Showing the first eight; more decompositions exist.
