Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737878, here are decompositions:

5 + 8737873 = 8737878
7 + 8737871 = 8737878
11 + 8737867 = 8737878
29 + 8737849 = 8737878
89 + 8737789 = 8737878
137 + 8737741 = 8737878
179 + 8737699 = 8737878
181 + 8737697 = 8737878

Showing the first eight; more decompositions exist.
