Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005148, here are decompositions:

5 + 1005143 = 1005148
17 + 1005131 = 1005148
41 + 1005107 = 1005148
47 + 1005101 = 1005148
107 + 1005041 = 1005148
167 + 1004981 = 1005148
401 + 1004747 = 1005148
461 + 1004687 = 1005148

Showing the first eight; more decompositions exist.
