Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90186, here are decompositions:

13 + 90173 = 90186
23 + 90163 = 90186
37 + 90149 = 90186
59 + 90127 = 90186
79 + 90107 = 90186
97 + 90089 = 90186
113 + 90073 = 90186
127 + 90059 = 90186

Showing the first eight; more decompositions exist.
