Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978422, here are decompositions:

19 + 978403 = 978422
73 + 978349 = 978422
79 + 978343 = 978422
139 + 978283 = 978422
199 + 978223 = 978422
241 + 978181 = 978422
271 + 978151 = 978422
331 + 978091 = 978422

Showing the first eight; more decompositions exist.
