Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30178, here are decompositions:
- 17 + 30161 = 30178
- 41 + 30137 = 30178
- 59 + 30119 = 30178
- 89 + 30089 = 30178
- 107 + 30071 = 30178
- 131 + 30047 = 30178
- 149 + 30029 = 30178
- 167 + 30011 = 30178
Showing the first eight; more decompositions exist.
