Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90168, here are decompositions:

5 + 90163 = 90168
19 + 90149 = 90168
41 + 90127 = 90168
47 + 90121 = 90168
61 + 90107 = 90168
79 + 90089 = 90168
97 + 90071 = 90168
101 + 90067 = 90168

Showing the first eight; more decompositions exist.
