Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90432, here are decompositions:

29 + 90403 = 90432
31 + 90401 = 90432
53 + 90379 = 90432
59 + 90373 = 90432
61 + 90371 = 90432
73 + 90359 = 90432
79 + 90353 = 90432
151 + 90281 = 90432

Showing the first eight; more decompositions exist.
