Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942940, here are decompositions:

23 + 942917 = 942940
41 + 942899 = 942940
71 + 942869 = 942940
83 + 942857 = 942940
113 + 942827 = 942940
191 + 942749 = 942940
281 + 942659 = 942940
347 + 942593 = 942940

Showing the first eight; more decompositions exist.
