Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90102, here are decompositions:

13 + 90089 = 90102
29 + 90073 = 90102
31 + 90071 = 90102
43 + 90059 = 90102
71 + 90031 = 90102
79 + 90023 = 90102
83 + 90019 = 90102
101 + 90001 = 90102

Showing the first eight; more decompositions exist.
