Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750878, here are decompositions:

5 + 8750873 = 8750878
11 + 8750867 = 8750878
47 + 8750831 = 8750878
107 + 8750771 = 8750878
239 + 8750639 = 8750878
347 + 8750531 = 8750878
359 + 8750519 = 8750878
431 + 8750447 = 8750878

Showing the first eight; more decompositions exist.
