Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69100, here are decompositions:

71 + 69029 = 69100
89 + 69011 = 69100
107 + 68993 = 69100
137 + 68963 = 69100
173 + 68927 = 69100
191 + 68909 = 69100
197 + 68903 = 69100
281 + 68819 = 69100

Showing the first eight; more decompositions exist.
