Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978748, here are decompositions:

5 + 978743 = 978748
59 + 978689 = 978748
101 + 978647 = 978748
131 + 978617 = 978748
137 + 978611 = 978748
149 + 978599 = 978748
179 + 978569 = 978748
227 + 978521 = 978748

Showing the first eight; more decompositions exist.
