Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978742, here are decompositions:

29 + 978713 = 978742
53 + 978689 = 978742
59 + 978683 = 978742
131 + 978611 = 978742
173 + 978569 = 978742
251 + 978491 = 978742
263 + 978479 = 978742
269 + 978473 = 978742

Showing the first eight; more decompositions exist.
