Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665198, here are decompositions:

5 + 8665193 = 8665198
41 + 8665157 = 8665198
89 + 8665109 = 8665198
167 + 8665031 = 8665198
239 + 8664959 = 8665198
251 + 8664947 = 8665198
257 + 8664941 = 8665198
467 + 8664731 = 8665198

Showing the first eight; more decompositions exist.
