Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69966, here are decompositions:
- 7 + 69959 = 69966
- 37 + 69929 = 69966
- 67 + 69899 = 69966
- 89 + 69877 = 69966
- 107 + 69859 = 69966
- 109 + 69857 = 69966
- 137 + 69829 = 69966
- 139 + 69827 = 69966
Showing the first eight; more decompositions exist.
