Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84100, here are decompositions:

11 + 84089 = 84100
41 + 84059 = 84100
47 + 84053 = 84100
53 + 84047 = 84100
83 + 84017 = 84100
89 + 84011 = 84100
113 + 83987 = 84100
131 + 83969 = 84100

Showing the first eight; more decompositions exist.
