Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938906, here are decompositions:

37 + 938869 = 938906
79 + 938827 = 938906
103 + 938803 = 938906
193 + 938713 = 938906
229 + 938677 = 938906
337 + 938569 = 938906
373 + 938533 = 938906
547 + 938359 = 938906

Showing the first eight; more decompositions exist.
