Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82130, here are decompositions:

79 + 82051 = 82130
109 + 82021 = 82130
127 + 82003 = 82130
157 + 81973 = 82130
163 + 81967 = 82130
193 + 81937 = 82130
199 + 81931 = 82130
211 + 81919 = 82130

Showing the first eight; more decompositions exist.
