Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756178, here are decompositions:

19 + 8756159 = 8756178
29 + 8756149 = 8756178
59 + 8756119 = 8756178
61 + 8756117 = 8756178
71 + 8756107 = 8756178
89 + 8756089 = 8756178
127 + 8756051 = 8756178
139 + 8756039 = 8756178

Showing the first eight; more decompositions exist.
