Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005672, here are decompositions:

11 + 1005661 = 1005672
29 + 1005643 = 1005672
53 + 1005619 = 1005672
79 + 1005593 = 1005672
131 + 1005541 = 1005672
179 + 1005493 = 1005672
191 + 1005481 = 1005672
233 + 1005439 = 1005672

Showing the first eight; more decompositions exist.
