Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82900, here are decompositions:

11 + 82889 = 82900
17 + 82883 = 82900
53 + 82847 = 82900
89 + 82811 = 82900
101 + 82799 = 82900
107 + 82793 = 82900
113 + 82787 = 82900
137 + 82763 = 82900

Showing the first eight; more decompositions exist.
