Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978904, here are decompositions:

41 + 978863 = 978904
53 + 978851 = 978904
83 + 978821 = 978904
107 + 978797 = 978904
131 + 978773 = 978904
191 + 978713 = 978904
257 + 978647 = 978904
293 + 978611 = 978904

Showing the first eight; more decompositions exist.
