Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757878, here are decompositions:

61 + 8757817 = 8757878
79 + 8757799 = 8757878
109 + 8757769 = 8757878
307 + 8757571 = 8757878
499 + 8757379 = 8757878
601 + 8757277 = 8757878
691 + 8757187 = 8757878
751 + 8757127 = 8757878

Showing the first eight; more decompositions exist.
