Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978550, here are decompositions:

29 + 978521 = 978550
59 + 978491 = 978550
71 + 978479 = 978550
101 + 978449 = 978550
137 + 978413 = 978550
191 + 978359 = 978550
227 + 978323 = 978550
263 + 978287 = 978550

Showing the first eight; more decompositions exist.
