Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665798, here are decompositions:

131 + 8665667 = 8665798
149 + 8665649 = 8665798
179 + 8665619 = 8665798
227 + 8665571 = 8665798
257 + 8665541 = 8665798
347 + 8665451 = 8665798
389 + 8665409 = 8665798
521 + 8665277 = 8665798

Showing the first eight; more decompositions exist.
