Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69900, here are decompositions:

23 + 69877 = 69900
41 + 69859 = 69900
43 + 69857 = 69900
53 + 69847 = 69900
67 + 69833 = 69900
71 + 69829 = 69900
73 + 69827 = 69900
79 + 69821 = 69900

Showing the first eight; more decompositions exist.
