Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90212, here are decompositions:
- 13 + 90199 = 90212
- 139 + 90073 = 90212
- 181 + 90031 = 90212
- 193 + 90019 = 90212
- 211 + 90001 = 90212
- 223 + 89989 = 90212
- 229 + 89983 = 90212
- 313 + 89899 = 90212
Showing the first eight; more decompositions exist.
