Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712808, here are decompositions:

29 + 8712779 = 8712808
47 + 8712761 = 8712808
59 + 8712749 = 8712808
107 + 8712701 = 8712808
131 + 8712677 = 8712808
179 + 8712629 = 8712808
197 + 8712611 = 8712808
311 + 8712497 = 8712808

Showing the first eight; more decompositions exist.
