Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755978, here are decompositions:

5 + 8755973 = 8755978
41 + 8755937 = 8755978
89 + 8755889 = 8755978
137 + 8755841 = 8755978
167 + 8755811 = 8755978
197 + 8755781 = 8755978
311 + 8755667 = 8755978
359 + 8755619 = 8755978

Showing the first eight; more decompositions exist.
