Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978156, here are decompositions:

5 + 978151 = 978156
7 + 978149 = 978156
43 + 978113 = 978156
79 + 978077 = 978156
83 + 978073 = 978156
89 + 978067 = 978156
103 + 978053 = 978156
107 + 978049 = 978156

Showing the first eight; more decompositions exist.
