Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942042, here are decompositions:

5 + 942037 = 942042
11 + 942031 = 942042
29 + 942013 = 942042
43 + 941999 = 942042
53 + 941989 = 942042
61 + 941981 = 942042
71 + 941971 = 942042
109 + 941933 = 942042

Showing the first eight; more decompositions exist.
