Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938388, here are decompositions:

19 + 938369 = 938388
29 + 938359 = 938388
37 + 938351 = 938388
41 + 938347 = 938388
47 + 938341 = 938388
79 + 938309 = 938388
109 + 938279 = 938388
131 + 938257 = 938388

Showing the first eight; more decompositions exist.
