Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90478, here are decompositions:

5 + 90473 = 90478
41 + 90437 = 90478
71 + 90407 = 90478
107 + 90371 = 90478
197 + 90281 = 90478
239 + 90239 = 90478
251 + 90227 = 90478
281 + 90197 = 90478

Showing the first eight; more decompositions exist.
