Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999392, here are decompositions:

3 + 999389 = 999392
61 + 999331 = 999392
193 + 999199 = 999392
211 + 999181 = 999392
223 + 999169 = 999392
349 + 999043 = 999392
409 + 998983 = 999392
613 + 998779 = 999392

Showing the first eight; more decompositions exist.
