Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999192, here are decompositions:

11 + 999181 = 999192
23 + 999169 = 999192
43 + 999149 = 999192
59 + 999133 = 999192
101 + 999091 = 999192
109 + 999083 = 999192
149 + 999043 = 999192
163 + 999029 = 999192

Showing the first eight; more decompositions exist.
