Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90086, here are decompositions:

13 + 90073 = 90086
19 + 90067 = 90086
67 + 90019 = 90086
79 + 90007 = 90086
97 + 89989 = 90086
103 + 89983 = 90086
109 + 89977 = 90086
127 + 89959 = 90086

Showing the first eight; more decompositions exist.
