Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999664, here are decompositions:

11 + 999653 = 999664
41 + 999623 = 999664
53 + 999611 = 999664
101 + 999563 = 999664
173 + 999491 = 999664
227 + 999437 = 999664
233 + 999431 = 999664
293 + 999371 = 999664

Showing the first eight; more decompositions exist.
