Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717878, here are decompositions:

5 + 8717873 = 8717878
11 + 8717867 = 8717878
17 + 8717861 = 8717878
131 + 8717747 = 8717878
137 + 8717741 = 8717878
347 + 8717531 = 8717878
677 + 8717201 = 8717878
761 + 8717117 = 8717878

Showing the first eight; more decompositions exist.
