Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979866, here are decompositions:

47 + 979819 = 979866
59 + 979807 = 979866
79 + 979787 = 979866
109 + 979757 = 979866
149 + 979717 = 979866
157 + 979709 = 979866
313 + 979553 = 979866
317 + 979549 = 979866

Showing the first eight; more decompositions exist.
