Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757198, here are decompositions:

7 + 8757191 = 8757198
11 + 8757187 = 8757198
19 + 8757179 = 8757198
67 + 8757131 = 8757198
71 + 8757127 = 8757198
89 + 8757109 = 8757198
137 + 8757061 = 8757198
139 + 8757059 = 8757198

Showing the first eight; more decompositions exist.
