Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90120, here are decompositions:

13 + 90107 = 90120
31 + 90089 = 90120
47 + 90073 = 90120
53 + 90067 = 90120
61 + 90059 = 90120
67 + 90053 = 90120
89 + 90031 = 90120
97 + 90023 = 90120

Showing the first eight; more decompositions exist.
