Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978108, here are decompositions:

17 + 978091 = 978108
29 + 978079 = 978108
31 + 978077 = 978108
37 + 978071 = 978108
41 + 978067 = 978108
59 + 978049 = 978108
67 + 978041 = 978108
71 + 978037 = 978108

Showing the first eight; more decompositions exist.
