Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99090, here are decompositions:

7 + 99083 = 99090
11 + 99079 = 99090
37 + 99053 = 99090
67 + 99023 = 99090
73 + 99017 = 99090
97 + 98993 = 99090
109 + 98981 = 99090
127 + 98963 = 99090

Showing the first eight; more decompositions exist.
