Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005448, here are decompositions:

11 + 1005437 = 1005448
89 + 1005359 = 1005448
131 + 1005317 = 1005448
179 + 1005269 = 1005448
239 + 1005209 = 1005448
317 + 1005131 = 1005448
347 + 1005101 = 1005448
419 + 1005029 = 1005448

Showing the first eight; more decompositions exist.
