Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938378, here are decompositions:

19 + 938359 = 938378
31 + 938347 = 938378
37 + 938341 = 938378
127 + 938251 = 938378
271 + 938107 = 938378
307 + 938071 = 938378
409 + 937969 = 938378
487 + 937891 = 938378

Showing the first eight; more decompositions exist.
