Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978170, here are decompositions:

13 + 978157 = 978170
19 + 978151 = 978170
79 + 978091 = 978170
97 + 978073 = 978170
103 + 978067 = 978170
139 + 978031 = 978170
163 + 978007 = 978170
199 + 977971 = 978170

Showing the first eight; more decompositions exist.
