Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942858, here are decompositions:

5 + 942853 = 942858
11 + 942847 = 942858
31 + 942827 = 942858
47 + 942811 = 942858
71 + 942787 = 942858
79 + 942779 = 942858
109 + 942749 = 942858
131 + 942727 = 942858

Showing the first eight; more decompositions exist.
