Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660394, here are decompositions:

7 + 8660387 = 8660394
11 + 8660383 = 8660394
13 + 8660381 = 8660394
97 + 8660297 = 8660394
103 + 8660291 = 8660394
107 + 8660287 = 8660394
131 + 8660263 = 8660394
167 + 8660227 = 8660394

Showing the first eight; more decompositions exist.
