Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979818, here are decompositions:

11 + 979807 = 979818
31 + 979787 = 979818
61 + 979757 = 979818
71 + 979747 = 979818
101 + 979717 = 979818
109 + 979709 = 979818
127 + 979691 = 979818
167 + 979651 = 979818

Showing the first eight; more decompositions exist.
