Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999372, here are decompositions:
- 13 + 999359 = 999372
- 41 + 999331 = 999372
- 43 + 999329 = 999372
- 103 + 999269 = 999372
- 139 + 999233 = 999372
- 151 + 999221 = 999372
- 173 + 999199 = 999372
- 191 + 999181 = 999372
Showing the first eight; more decompositions exist.
