Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978774, here are decompositions:

31 + 978743 = 978774
47 + 978727 = 978774
61 + 978713 = 978774
127 + 978647 = 978774
131 + 978643 = 978774
157 + 978617 = 978774
163 + 978611 = 978774
233 + 978541 = 978774

Showing the first eight; more decompositions exist.
