Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82912, here are decompositions:

23 + 82889 = 82912
29 + 82883 = 82912
101 + 82811 = 82912
113 + 82799 = 82912
131 + 82781 = 82912
149 + 82763 = 82912
191 + 82721 = 82912
293 + 82619 = 82912

Showing the first eight; more decompositions exist.
