Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90438, here are decompositions:

31 + 90407 = 90438
37 + 90401 = 90438
41 + 90397 = 90438
59 + 90379 = 90438
67 + 90371 = 90438
79 + 90359 = 90438
149 + 90289 = 90438
157 + 90281 = 90438

Showing the first eight; more decompositions exist.
