Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005730, here are decompositions:

29 + 1005701 = 1005730
53 + 1005677 = 1005730
83 + 1005647 = 1005730
113 + 1005617 = 1005730
137 + 1005593 = 1005730
149 + 1005581 = 1005730
179 + 1005551 = 1005730
227 + 1005503 = 1005730

Showing the first eight; more decompositions exist.
