Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938838, here are decompositions:

7 + 938831 = 938838
11 + 938827 = 938838
31 + 938807 = 938838
157 + 938681 = 938838
179 + 938659 = 938838
227 + 938611 = 938838
269 + 938569 = 938838
331 + 938507 = 938838

Showing the first eight; more decompositions exist.
