Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99966, here are decompositions:
- 5 + 99961 = 99966
- 37 + 99929 = 99966
- 43 + 99923 = 99966
- 59 + 99907 = 99966
- 89 + 99877 = 99966
- 107 + 99859 = 99966
- 127 + 99839 = 99966
- 137 + 99829 = 99966
Showing the first eight; more decompositions exist.
