Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978442, here are decompositions:

29 + 978413 = 978442
53 + 978389 = 978442
83 + 978359 = 978442
173 + 978269 = 978442
233 + 978209 = 978442
239 + 978203 = 978442
263 + 978179 = 978442
293 + 978149 = 978442

Showing the first eight; more decompositions exist.
