Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938678, here are decompositions:

19 + 938659 = 938678
61 + 938617 = 938678
67 + 938611 = 938678
109 + 938569 = 938678
241 + 938437 = 938678
331 + 938347 = 938678
337 + 938341 = 938678
421 + 938257 = 938678

Showing the first eight; more decompositions exist.
