Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005442, here are decompositions:

3 + 1005439 = 1005442
5 + 1005437 = 1005442
29 + 1005413 = 1005442
71 + 1005371 = 1005442
83 + 1005359 = 1005442
149 + 1005293 = 1005442
173 + 1005269 = 1005442
233 + 1005209 = 1005442

Showing the first eight; more decompositions exist.
