Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005722, here are decompositions:

13 + 1005709 = 1005722
43 + 1005679 = 1005722
61 + 1005661 = 1005722
79 + 1005643 = 1005722
103 + 1005619 = 1005722
181 + 1005541 = 1005722
229 + 1005493 = 1005722
241 + 1005481 = 1005722

Showing the first eight; more decompositions exist.
