Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99100, here are decompositions:

11 + 99089 = 99100
17 + 99083 = 99100
47 + 99053 = 99100
59 + 99041 = 99100
83 + 99017 = 99100
101 + 98999 = 99100
107 + 98993 = 99100
137 + 98963 = 99100

Showing the first eight; more decompositions exist.
