Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977178, here are decompositions:

11 + 977167 = 977178
29 + 977149 = 977178
31 + 977147 = 977178
71 + 977107 = 977178
109 + 977069 = 977178
131 + 977047 = 977178
157 + 977021 = 977178
227 + 976951 = 977178

Showing the first eight; more decompositions exist.
