Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69000, here are decompositions:

7 + 68993 = 69000
37 + 68963 = 69000
53 + 68947 = 69000
73 + 68927 = 69000
83 + 68917 = 69000
97 + 68903 = 69000
101 + 68899 = 69000
103 + 68897 = 69000

Showing the first eight; more decompositions exist.
