Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30220, here are decompositions:
- 17 + 30203 = 30220
- 23 + 30197 = 30220
- 59 + 30161 = 30220
- 83 + 30137 = 30220
- 101 + 30119 = 30220
- 107 + 30113 = 30220
- 131 + 30089 = 30220
- 149 + 30071 = 30220
Showing the first eight; more decompositions exist.
