Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978850, here are decompositions:

11 + 978839 = 978850
29 + 978821 = 978850
53 + 978797 = 978850
101 + 978749 = 978850
107 + 978743 = 978850
137 + 978713 = 978850
167 + 978683 = 978850
233 + 978617 = 978850

Showing the first eight; more decompositions exist.
