Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999078, here are decompositions:

11 + 999067 = 999078
29 + 999049 = 999078
71 + 999007 = 999078
89 + 998989 = 999078
109 + 998969 = 999078
127 + 998951 = 999078
131 + 998947 = 999078
137 + 998941 = 999078

Showing the first eight; more decompositions exist.
