Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978772, here are decompositions:

23 + 978749 = 978772
29 + 978743 = 978772
59 + 978713 = 978772
83 + 978689 = 978772
89 + 978683 = 978772
173 + 978599 = 978772
251 + 978521 = 978772
281 + 978491 = 978772

Showing the first eight; more decompositions exist.
