Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111216, here are decompositions:
- 5 + 111211 = 111216
- 29 + 111187 = 111216
- 67 + 111149 = 111216
- 73 + 111143 = 111216
- 89 + 111127 = 111216
- 97 + 111119 = 111216
- 107 + 111109 = 111216
- 113 + 111103 = 111216
Showing the first eight; more decompositions exist.
