Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978188, here are decompositions:

7 + 978181 = 978188
31 + 978157 = 978188
37 + 978151 = 978188
97 + 978091 = 978188
109 + 978079 = 978188
139 + 978049 = 978188
151 + 978037 = 978188
157 + 978031 = 978188

Showing the first eight; more decompositions exist.
