Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756878, here are decompositions:

41 + 8756837 = 8756878
71 + 8756807 = 8756878
89 + 8756789 = 8756878
107 + 8756771 = 8756878
191 + 8756687 = 8756878
269 + 8756609 = 8756878
311 + 8756567 = 8756878
359 + 8756519 = 8756878

Showing the first eight; more decompositions exist.
