Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984638, here are decompositions:

97 + 984541 = 984638
157 + 984481 = 984638
181 + 984457 = 984638
211 + 984427 = 984638
241 + 984397 = 984638
271 + 984367 = 984638
331 + 984307 = 984638
337 + 984301 = 984638

Showing the first eight; more decompositions exist.
