Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90528, here are decompositions:

5 + 90523 = 90528
17 + 90511 = 90528
29 + 90499 = 90528
47 + 90481 = 90528
59 + 90469 = 90528
89 + 90439 = 90528
127 + 90401 = 90528
131 + 90397 = 90528

Showing the first eight; more decompositions exist.
