Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005724, here are decompositions:

23 + 1005701 = 1005724
47 + 1005677 = 1005724
107 + 1005617 = 1005724
131 + 1005593 = 1005724
173 + 1005551 = 1005724
197 + 1005527 = 1005724
257 + 1005467 = 1005724
311 + 1005413 = 1005724

Showing the first eight; more decompositions exist.
