Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978814, here are decompositions:

17 + 978797 = 978814
41 + 978773 = 978814
71 + 978743 = 978814
101 + 978713 = 978814
131 + 978683 = 978814
167 + 978647 = 978814
197 + 978617 = 978814
293 + 978521 = 978814

Showing the first eight; more decompositions exist.
