Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942742, here are decompositions:

23 + 942719 = 942742
83 + 942659 = 942742
89 + 942653 = 942742
149 + 942593 = 942742
173 + 942569 = 942742
233 + 942509 = 942742
263 + 942479 = 942742
293 + 942449 = 942742

Showing the first eight; more decompositions exist.
