Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942840, here are decompositions:

13 + 942827 = 942840
29 + 942811 = 942840
53 + 942787 = 942840
61 + 942779 = 942840
113 + 942727 = 942840
131 + 942709 = 942840
149 + 942691 = 942840
179 + 942661 = 942840

Showing the first eight; more decompositions exist.
