Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69888, here are decompositions:

11 + 69877 = 69888
29 + 69859 = 69888
31 + 69857 = 69888
41 + 69847 = 69888
59 + 69829 = 69888
61 + 69827 = 69888
67 + 69821 = 69888
79 + 69809 = 69888

Showing the first eight; more decompositions exist.
