Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978822, here are decompositions:

23 + 978799 = 978822
73 + 978749 = 978822
79 + 978743 = 978822
109 + 978713 = 978822
139 + 978683 = 978822
179 + 978643 = 978822
211 + 978611 = 978822
223 + 978599 = 978822

Showing the first eight; more decompositions exist.
