Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005146, here are decompositions:

3 + 1005143 = 1005146
13 + 1005133 = 1005146
67 + 1005079 = 1005146
73 + 1005073 = 1005146
97 + 1005049 = 1005146
127 + 1005019 = 1005146
139 + 1005007 = 1005146
229 + 1004917 = 1005146

Showing the first eight; more decompositions exist.
