Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90550, here are decompositions:

3 + 90547 = 90550
17 + 90533 = 90550
23 + 90527 = 90550
113 + 90437 = 90550
149 + 90401 = 90550
179 + 90371 = 90550
191 + 90359 = 90550
197 + 90353 = 90550

Showing the first eight; more decompositions exist.
