Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942878, here are decompositions:

19 + 942859 = 942878
31 + 942847 = 942878
67 + 942811 = 942878
151 + 942727 = 942878
241 + 942637 = 942878
271 + 942607 = 942878
337 + 942541 = 942878
439 + 942439 = 942878

Showing the first eight; more decompositions exist.
