Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013942, here are decompositions:

19 + 1013923 = 1013942
43 + 1013899 = 1013942
103 + 1013839 = 1013942
109 + 1013833 = 1013942
151 + 1013791 = 1013942
229 + 1013713 = 1013942
271 + 1013671 = 1013942
313 + 1013629 = 1013942

Showing the first eight; more decompositions exist.
