Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978784, here are decompositions:

11 + 978773 = 978784
41 + 978743 = 978784
71 + 978713 = 978784
101 + 978683 = 978784
137 + 978647 = 978784
167 + 978617 = 978784
173 + 978611 = 978784
263 + 978521 = 978784

Showing the first eight; more decompositions exist.
