Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942806, here are decompositions:

19 + 942787 = 942806
43 + 942763 = 942806
79 + 942727 = 942806
97 + 942709 = 942806
199 + 942607 = 942806
223 + 942583 = 942806
229 + 942577 = 942806
367 + 942439 = 942806

Showing the first eight; more decompositions exist.
