Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747808, here are decompositions:

5 + 8747803 = 8747808
19 + 8747789 = 8747808
31 + 8747777 = 8747808
61 + 8747747 = 8747808
71 + 8747737 = 8747808
107 + 8747701 = 8747808
131 + 8747677 = 8747808
191 + 8747617 = 8747808

Showing the first eight; more decompositions exist.
