Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938488, here are decompositions:

29 + 938459 = 938488
41 + 938447 = 938488
101 + 938387 = 938488
137 + 938351 = 938488
179 + 938309 = 938488
269 + 938219 = 938488
281 + 938207 = 938488
359 + 938129 = 938488

Showing the first eight; more decompositions exist.
