Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999186, here are decompositions:

5 + 999181 = 999186
17 + 999169 = 999186
37 + 999149 = 999186
53 + 999133 = 999186
103 + 999083 = 999186
137 + 999049 = 999186
157 + 999029 = 999186
163 + 999023 = 999186

Showing the first eight; more decompositions exist.
