Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69018, here are decompositions:
- 7 + 69011 = 69018
- 17 + 69001 = 69018
- 71 + 68947 = 69018
- 101 + 68917 = 69018
- 109 + 68909 = 69018
- 127 + 68891 = 69018
- 137 + 68881 = 69018
- 139 + 68879 = 69018
Showing the first eight; more decompositions exist.
