Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938738, here are decompositions:

61 + 938677 = 938738
79 + 938659 = 938738
127 + 938611 = 938738
379 + 938359 = 938738
397 + 938341 = 938738
487 + 938251 = 938738
631 + 938107 = 938738
769 + 937969 = 938738

Showing the first eight; more decompositions exist.
