Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747868, here are decompositions:

5 + 8747863 = 8747868
11 + 8747857 = 8747868
37 + 8747831 = 8747868
61 + 8747807 = 8747868
79 + 8747789 = 8747868
109 + 8747759 = 8747868
131 + 8747737 = 8747868
167 + 8747701 = 8747868

Showing the first eight; more decompositions exist.
