Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65180, here are decompositions:

7 + 65173 = 65180
13 + 65167 = 65180
61 + 65119 = 65180
79 + 65101 = 65180
109 + 65071 = 65180
127 + 65053 = 65180
151 + 65029 = 65180
211 + 64969 = 65180

Showing the first eight; more decompositions exist.
