Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999138, here are decompositions:

5 + 999133 = 999138
37 + 999101 = 999138
47 + 999091 = 999138
71 + 999067 = 999138
89 + 999049 = 999138
109 + 999029 = 999138
131 + 999007 = 999138
149 + 998989 = 999138

Showing the first eight; more decompositions exist.
