Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90930, here are decompositions:

13 + 90917 = 90930
19 + 90911 = 90930
23 + 90907 = 90930
29 + 90901 = 90930
43 + 90887 = 90930
67 + 90863 = 90930
83 + 90847 = 90930
89 + 90841 = 90930

Showing the first eight; more decompositions exist.
