Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30210, here are decompositions:
- 7 + 30203 = 30210
- 13 + 30197 = 30210
- 23 + 30187 = 30210
- 29 + 30181 = 30210
- 41 + 30169 = 30210
- 71 + 30139 = 30210
- 73 + 30137 = 30210
- 97 + 30113 = 30210
Showing the first eight; more decompositions exist.
