Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999366, here are decompositions:

7 + 999359 = 999366
37 + 999329 = 999366
59 + 999307 = 999366
79 + 999287 = 999366
97 + 999269 = 999366
127 + 999239 = 999366
149 + 999217 = 999366
167 + 999199 = 999366

Showing the first eight; more decompositions exist.
