Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999400, here are decompositions:

11 + 999389 = 999400
23 + 999377 = 999400
29 + 999371 = 999400
41 + 999359 = 999400
71 + 999329 = 999400
113 + 999287 = 999400
131 + 999269 = 999400
167 + 999233 = 999400

Showing the first eight; more decompositions exist.
