Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999164, here are decompositions:

31 + 999133 = 999164
73 + 999091 = 999164
97 + 999067 = 999164
157 + 999007 = 999164
181 + 998983 = 999164
223 + 998941 = 999164
307 + 998857 = 999164
421 + 998743 = 999164

Showing the first eight; more decompositions exist.
