Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90238, here are decompositions:

11 + 90227 = 90238
41 + 90197 = 90238
47 + 90191 = 90238
89 + 90149 = 90238
131 + 90107 = 90238
149 + 90089 = 90238
167 + 90071 = 90238
179 + 90059 = 90238

Showing the first eight; more decompositions exist.
