Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90144, here are decompositions:

17 + 90127 = 90144
23 + 90121 = 90144
37 + 90107 = 90144
71 + 90073 = 90144
73 + 90071 = 90144
113 + 90031 = 90144
127 + 90017 = 90144
137 + 90007 = 90144

Showing the first eight; more decompositions exist.
