Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90100, here are decompositions:

11 + 90089 = 90100
29 + 90071 = 90100
41 + 90059 = 90100
47 + 90053 = 90100
83 + 90017 = 90100
89 + 90011 = 90100
137 + 89963 = 90100
191 + 89909 = 90100

Showing the first eight; more decompositions exist.
