Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98100, here are decompositions:

19 + 98081 = 98100
43 + 98057 = 98100
53 + 98047 = 98100
59 + 98041 = 98100
83 + 98017 = 98100
89 + 98011 = 98100
113 + 97987 = 98100
127 + 97973 = 98100

Showing the first eight; more decompositions exist.
