Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999170, here are decompositions:

37 + 999133 = 999170
79 + 999091 = 999170
103 + 999067 = 999170
127 + 999043 = 999170
163 + 999007 = 999170
181 + 998989 = 999170
223 + 998947 = 999170
229 + 998941 = 999170

Showing the first eight; more decompositions exist.
