Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732878, here are decompositions:

17 + 8732861 = 8732878
47 + 8732831 = 8732878
59 + 8732819 = 8732878
71 + 8732807 = 8732878
191 + 8732687 = 8732878
239 + 8732639 = 8732878
251 + 8732627 = 8732878
389 + 8732489 = 8732878

Showing the first eight; more decompositions exist.
