Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69006, here are decompositions:
- 5 + 69001 = 69006
- 13 + 68993 = 69006
- 43 + 68963 = 69006
- 59 + 68947 = 69006
- 79 + 68927 = 69006
- 89 + 68917 = 69006
- 97 + 68909 = 69006
- 103 + 68903 = 69006
Showing the first eight; more decompositions exist.
