Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942728, here are decompositions:

19 + 942709 = 942728
37 + 942691 = 942728
67 + 942661 = 942728
151 + 942577 = 942728
541 + 942187 = 942728
691 + 942037 = 942728
739 + 941989 = 942728
757 + 941971 = 942728

Showing the first eight; more decompositions exist.
