Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978522, here are decompositions:

11 + 978511 = 978522
31 + 978491 = 978522
43 + 978479 = 978522
59 + 978463 = 978522
73 + 978449 = 978522
109 + 978413 = 978522
163 + 978359 = 978522
173 + 978349 = 978522

Showing the first eight; more decompositions exist.
