Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942986, here are decompositions:

3 + 942983 = 942986
7 + 942979 = 942986
43 + 942943 = 942986
97 + 942889 = 942986
103 + 942883 = 942986
127 + 942859 = 942986
139 + 942847 = 942986
199 + 942787 = 942986

Showing the first eight; more decompositions exist.
