Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978556, here are decompositions:

83 + 978473 = 978556
107 + 978449 = 978556
167 + 978389 = 978556
197 + 978359 = 978556
233 + 978323 = 978556
269 + 978287 = 978556
317 + 978239 = 978556
347 + 978209 = 978556

Showing the first eight; more decompositions exist.
