Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938138, here are decompositions:

31 + 938107 = 938138
67 + 938071 = 938138
79 + 938059 = 938138
211 + 937927 = 938138
337 + 937801 = 938138
349 + 937789 = 938138
457 + 937681 = 938138
499 + 937639 = 938138

Showing the first eight; more decompositions exist.
