Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942870, here are decompositions:

11 + 942859 = 942870
13 + 942857 = 942870
17 + 942853 = 942870
23 + 942847 = 942870
43 + 942827 = 942870
59 + 942811 = 942870
83 + 942787 = 942870
107 + 942763 = 942870

Showing the first eight; more decompositions exist.
