Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938648, here are decompositions:

31 + 938617 = 938648
37 + 938611 = 938648
79 + 938569 = 938648
157 + 938491 = 938648
211 + 938437 = 938648
307 + 938341 = 938648
397 + 938251 = 938648
541 + 938107 = 938648

Showing the first eight; more decompositions exist.
