Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90286, here are decompositions:

5 + 90281 = 90286
23 + 90263 = 90286
47 + 90239 = 90286
59 + 90227 = 90286
83 + 90203 = 90286
89 + 90197 = 90286
113 + 90173 = 90286
137 + 90149 = 90286

Showing the first eight; more decompositions exist.
