Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939242, here are decompositions:

13 + 939229 = 939242
61 + 939181 = 939242
151 + 939091 = 939242
181 + 939061 = 939242
223 + 939019 = 939242
373 + 938869 = 939242
439 + 938803 = 939242
631 + 938611 = 939242

Showing the first eight; more decompositions exist.
