Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005548, here are decompositions:

7 + 1005541 = 1005548
67 + 1005481 = 1005548
109 + 1005439 = 1005548
139 + 1005409 = 1005548
157 + 1005391 = 1005548
199 + 1005349 = 1005548
307 + 1005241 = 1005548
331 + 1005217 = 1005548

Showing the first eight; more decompositions exist.
