Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942866, here are decompositions:

7 + 942859 = 942866
13 + 942853 = 942866
19 + 942847 = 942866
79 + 942787 = 942866
103 + 942763 = 942866
139 + 942727 = 942866
157 + 942709 = 942866
229 + 942637 = 942866

Showing the first eight; more decompositions exist.
