Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979830, here are decompositions:

11 + 979819 = 979830
23 + 979807 = 979830
43 + 979787 = 979830
73 + 979757 = 979830
83 + 979747 = 979830
113 + 979717 = 979830
139 + 979691 = 979830
179 + 979651 = 979830

Showing the first eight; more decompositions exist.
