Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30430, here are decompositions:
- 3 + 30427 = 30430
- 41 + 30389 = 30430
- 83 + 30347 = 30430
- 89 + 30341 = 30430
- 107 + 30323 = 30430
- 137 + 30293 = 30430
- 227 + 30203 = 30430
- 233 + 30197 = 30430
Showing the first eight; more decompositions exist.
