Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30228, here are decompositions:
- 5 + 30223 = 30228
- 17 + 30211 = 30228
- 31 + 30197 = 30228
- 41 + 30187 = 30228
- 47 + 30181 = 30228
- 59 + 30169 = 30228
- 67 + 30161 = 30228
- 89 + 30139 = 30228
Showing the first eight; more decompositions exist.
