Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999966, here are decompositions:
- 5 + 999961 = 999966
- 7 + 999959 = 999966
- 13 + 999953 = 999966
- 59 + 999907 = 999966
- 83 + 999883 = 999966
- 103 + 999863 = 999966
- 113 + 999853 = 999966
- 157 + 999809 = 999966
Showing the first eight; more decompositions exist.
