Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99212, here are decompositions:
- 31 + 99181 = 99212
- 73 + 99139 = 99212
- 79 + 99133 = 99212
- 103 + 99109 = 99212
- 109 + 99103 = 99212
- 199 + 99013 = 99212
- 283 + 98929 = 99212
- 313 + 98899 = 99212
Showing the first eight; more decompositions exist.
