Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938394, here are decompositions:

7 + 938387 = 938394
43 + 938351 = 938394
47 + 938347 = 938394
53 + 938341 = 938394
71 + 938323 = 938394
101 + 938293 = 938394
131 + 938263 = 938394
137 + 938257 = 938394

Showing the first eight; more decompositions exist.
