Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978160, here are decompositions:

3 + 978157 = 978160
11 + 978149 = 978160
47 + 978113 = 978160
83 + 978077 = 978160
89 + 978071 = 978160
107 + 978053 = 978160
149 + 978011 = 978160
233 + 977927 = 978160

Showing the first eight; more decompositions exist.
