Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90490, here are decompositions:

17 + 90473 = 90490
53 + 90437 = 90490
83 + 90407 = 90490
89 + 90401 = 90490
131 + 90359 = 90490
137 + 90353 = 90490
227 + 90263 = 90490
251 + 90239 = 90490

Showing the first eight; more decompositions exist.
