Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69180, here are decompositions:

17 + 69163 = 69180
29 + 69151 = 69180
31 + 69149 = 69180
37 + 69143 = 69180
53 + 69127 = 69180
61 + 69119 = 69180
71 + 69109 = 69180
107 + 69073 = 69180

Showing the first eight; more decompositions exist.
