Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30442, here are decompositions:
- 11 + 30431 = 30442
- 53 + 30389 = 30442
- 101 + 30341 = 30442
- 149 + 30293 = 30442
- 173 + 30269 = 30442
- 239 + 30203 = 30442
- 281 + 30161 = 30442
- 353 + 30089 = 30442
Showing the first eight; more decompositions exist.
