Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978562, here are decompositions:

41 + 978521 = 978562
71 + 978491 = 978562
83 + 978479 = 978562
89 + 978473 = 978562
113 + 978449 = 978562
149 + 978413 = 978562
173 + 978389 = 978562
239 + 978323 = 978562

Showing the first eight; more decompositions exist.
