Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999126, here are decompositions:

43 + 999083 = 999126
59 + 999067 = 999126
83 + 999043 = 999126
97 + 999029 = 999126
103 + 999023 = 999126
137 + 998989 = 999126
157 + 998969 = 999126
179 + 998947 = 999126

Showing the first eight; more decompositions exist.
