Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747898, here are decompositions:

7 + 8747891 = 8747898
41 + 8747857 = 8747898
67 + 8747831 = 8747898
79 + 8747819 = 8747898
109 + 8747789 = 8747898
139 + 8747759 = 8747898
151 + 8747747 = 8747898
197 + 8747701 = 8747898

Showing the first eight; more decompositions exist.
