Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499968, here are decompositions:
- 11 + 499957 = 499968
- 41 + 499927 = 499968
- 71 + 499897 = 499968
- 89 + 499879 = 499968
- 149 + 499819 = 499968
- 167 + 499801 = 499968
- 181 + 499787 = 499968
- 229 + 499739 = 499968
Showing the first eight; more decompositions exist.
