Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99216, here are decompositions:
- 43 + 99173 = 99216
- 67 + 99149 = 99216
- 79 + 99137 = 99216
- 83 + 99133 = 99216
- 97 + 99119 = 99216
- 107 + 99109 = 99216
- 113 + 99103 = 99216
- 127 + 99089 = 99216
Showing the first eight; more decompositions exist.
