Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005544, here are decompositions:

3 + 1005541 = 1005544
17 + 1005527 = 1005544
41 + 1005503 = 1005544
107 + 1005437 = 1005544
131 + 1005413 = 1005544
173 + 1005371 = 1005544
227 + 1005317 = 1005544
251 + 1005293 = 1005544

Showing the first eight; more decompositions exist.
