Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979878, here are decompositions:

5 + 979873 = 979878
47 + 979831 = 979878
59 + 979819 = 979878
71 + 979807 = 979878
131 + 979747 = 979878
227 + 979651 = 979878
311 + 979567 = 979878
337 + 979541 = 979878

Showing the first eight; more decompositions exist.
