Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978744, here are decompositions:

17 + 978727 = 978744
31 + 978713 = 978744
47 + 978697 = 978744
61 + 978683 = 978744
97 + 978647 = 978744
101 + 978643 = 978744
127 + 978617 = 978744
223 + 978521 = 978744

Showing the first eight; more decompositions exist.
