Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12228, here are decompositions:
- 17 + 12211 = 12228
- 31 + 12197 = 12228
- 67 + 12161 = 12228
- 71 + 12157 = 12228
- 79 + 12149 = 12228
- 109 + 12119 = 12228
- 127 + 12101 = 12228
- 131 + 12097 = 12228
Showing the first eight; more decompositions exist.
