Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978738, here are decompositions:

11 + 978727 = 978738
41 + 978697 = 978738
127 + 978611 = 978738
139 + 978599 = 978738
197 + 978541 = 978738
227 + 978511 = 978738
281 + 978457 = 978738
311 + 978427 = 978738

Showing the first eight; more decompositions exist.
