Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938370, here are decompositions:

11 + 938359 = 938370
19 + 938351 = 938370
23 + 938347 = 938370
29 + 938341 = 938370
47 + 938323 = 938370
61 + 938309 = 938370
107 + 938263 = 938370
113 + 938257 = 938370

Showing the first eight; more decompositions exist.
