Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90108, here are decompositions:

19 + 90089 = 90108
37 + 90071 = 90108
41 + 90067 = 90108
89 + 90019 = 90108
97 + 90011 = 90108
101 + 90007 = 90108
107 + 90001 = 90108
131 + 89977 = 90108

Showing the first eight; more decompositions exist.
