Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978124, here are decompositions:

11 + 978113 = 978124
47 + 978077 = 978124
53 + 978071 = 978124
71 + 978053 = 978124
83 + 978041 = 978124
107 + 978017 = 978124
113 + 978011 = 978124
197 + 977927 = 978124

Showing the first eight; more decompositions exist.
