Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005378, here are decompositions:

5 + 1005373 = 1005378
7 + 1005371 = 1005378
19 + 1005359 = 1005378
29 + 1005349 = 1005378
47 + 1005331 = 1005378
61 + 1005317 = 1005378
109 + 1005269 = 1005378
137 + 1005241 = 1005378

Showing the first eight; more decompositions exist.
