Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79828, here are decompositions:

5 + 79823 = 79828
11 + 79817 = 79828
17 + 79811 = 79828
59 + 79769 = 79828
71 + 79757 = 79828
131 + 79697 = 79828
137 + 79691 = 79828
197 + 79631 = 79828

Showing the first eight; more decompositions exist.
