Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005372, here are decompositions:

13 + 1005359 = 1005372
23 + 1005349 = 1005372
41 + 1005331 = 1005372
59 + 1005313 = 1005372
79 + 1005293 = 1005372
103 + 1005269 = 1005372
131 + 1005241 = 1005372
149 + 1005223 = 1005372

Showing the first eight; more decompositions exist.
